The Energetic Heart:
Bioelectromagnetic Interactions Within and Between People
Rollin McCraty, Ph.D.
Man’s perceptions are not bounded by organs of perception; he perceives far more
than sense (tho’ ever so acute) can discover. —William Blake
This paper will focus on electromagnetic fields
generated by the heart that permeate every cell and
may act as a synchronizing signal for the body in a
manner analogous to information carried by radio
waves. Particular emphasis will be devoted to evi-
dence demonstrating that this energy is not only
transmitted internally to the brain but is also de-
tectable by others within its range of communica-
tion. Finally, data will be discussed indicating that
cells studied in vitro are also responsive to the heart’s
bioelectromagnetic field.
The heart generates the largest electromag-
netic field in the body. The electrical field as mea-
sured in an electrocardiogram (ECG) is about 60
times greater in amplitude than the brain waves re-
corded in an electroencephalogram (EEG). The
magnetic component of the heart’s field, which is
around 5000 times stronger than that produced by
the brain, is not impeded by tissues and can be mea-
sured several feet away from the body with Super-
conducting Quantum Interference Device (SQUID)-
based magnetometers.1 We have also found that the
clear rhythmic patterns in beat-to-beat heart rate
variability are distinctly altered when different emo-
tions are experienced. These changes in electromag-
netic, sound pressure, and blood pressure waves pro-
duced by cardiac rhythmic activity are “felt” by ev-
ery cell in the body, further supporting the heart’s
role as a global internal synchronizing signal.
Biological Patterns Encode Information
One of the primary ways that signals and mes-
sages are encoded and transmitted in physiological
systems is in the language of patterns. In the ner-
vous system, it is well established that information
is encoded in the time intervals between action po-
tentials—patterns of electrical activity—and this may
also apply to humoral communications. Several re-
cent studies have revealed that biologically relevant
information is encoded in the time interval between
hormonal pulses.2-4 As the heart secretes a number
of different hormones with each contraction, there
is a hormonal pulse pattern that correlates with heart
rhythms. In addition to the encoding of information
in the space between nerve impulses and in the in-
tervals between hormonal pulses, it is likely that in-
formation is also encoded in the interbeat intervals
of the pressure and electromagnetic waves produced
by the heart. Karl Pribram has proposed that the low-
frequency oscillations generated by the heart and
body in the form of afferent neural, hormonal, and
electrical patterns are the carriers of emotional in-
formation, and that the higher frequency oscillations
found in the EEG reflect the conscious perception
and labeling of feelings and emotions.5
Detecting Bioelectromagnetic Patterns Using Signal
Averaging
A useful technique for detecting patterns in
biological systems and investigating a number of
bioelectromagnetic phenomena is signal averaging.
This is accomplished by superimposing any number
of equal-length epochs, each of which contains a re-
peating periodic signal. This emphasizes and distin-
guishes any signal that is time-locked to the periodic
signal while eliminating variations that are not time-
locked to the periodic signal. This procedure is com-

monly used to detect and record cerebral cortical
responses to sensory stimulation.6 When signal av-
eraging is used to detect activity in the EEG that is
time-locked to the ECG, the resultant waveform is
called the heartbeat evoked potential.
The Heartbeat Evoked Potential
In looking at heartbeat evoked potential data,
it can be seen that the electromagnetic signal arrives
at the brain instantaneously, while a host of differ-
ent neural signals reach the brain starting about 8
milliseconds later and continue arriving throughout
the cardiac cycle. Although the precise timing var-
ies with each cycle, at around 240 milliseconds the
blood pressure wave arrives at the brain and acts to
synchronize neural activity, especially the alpha
rhythm. It is also possible that information is en-
coded in the shape (modulation) of the ECG wave
itself. For example, if one examines consecutive ECG
cycles, it can be seen that each wave is slightly var-
ied in a complex manner.
As indicated, the heart generates a powerful
pressure wave that travels rapidly throughout the
arteries much faster than the actual flow of blood
that we feel as our pulse. These pressure waves force
the blood cells through the capillaries to provide
oxygen and nutrients to cells and expand the arter-

ies, causing them to generate a relatively large elec-
trical voltage. These waves also apply pressure to
the cells in a rhythmic fashion that can cause some
of their proteins to generate an electrical current in
response to this “squeeze.” Experiments conducted
in our laboratory have shown that a change in the
brain’s electrical activity can be seen when the blood
pressure wave reaches the brain around 240 milli-
seconds after systole.
There is a replicable and complex distribution
of heartbeat evoked potentials across the scalp.
Changes in these evoked potentials associated with
the heart’s afferent neurological input to the brain
are detectable between 50 to 550 milliseconds after
the heartbeat.7 Gary Schwartz and colleagues at the
University of Arizona believe the earlier components
in this complex distribution cannot be explained by
simple physiological mechanisms alone and suggest
that an energetic interaction between the heart and
brain also occurs.8 They have confirmed our find-
ings that heart-focused attention is associated with
increased heart-brain synchrony, providing further
support for energetic heart-brain communications.
Schwartz and colleagues also demonstrated that
Figure 1. Signal averaging.
The sequence of the signal averaging procedure is shown above.
First, the signals recorded from the EEG and ECG are digitized
and stored in a computer. The R-wave (peak) of the ECG is
used as the time reference for cutting the EEG and ECG signals
into individual segments. The individual segments are then
averaged together to produce the resultant waveforms. Only
signals that are repeatedly synchronous with the ECG are present
in the resulting waveform. Signals not related to the signal source
(ECG) are eliminated through this process.
Figure 2. Heartbeat evoked potentials.
This figure shows an example of typical heartbeat evoked
potentials. In this example, 450 averages were used. The pulse
wave is also shown, indicating the timing relationship of the
blood pressure wave reaching the brain. In this example, there
is less synchronized alpha activity immediately after the R-
wave. The time range between 10 and 250 milliseconds is
when afferent signals from the heart are impinging upon the
brain, and the alpha desynchronization indicates the processing
of this information. Increased alpha activity can be clearly seen
later in the waveforms, starting at around the time the blood
pressure wave reaches the brain.

when subjects focused their attention on the per-
ception of their heartbeat, the synchrony in the
preventricular region of the heartbeat evoked poten-
tial increased. From this they concluded that
preventricular synchrony may reflect an energetic
mechanism of heart-brain communication, while
postventricular synchrony most likely reflects direct
physiological mechanisms.8
The Heart’s Role in Emotion
Throughout the 1990s, the view that the brain
and body work in conjunction in order for percep-
tions, thoughts, and emotions to emerge gained mo-
mentum and is now widely accepted. The brain is an
analog processor that relates whole concepts (pat-
terns) to one another and looks for similarities, dif-
ferences, or relationships between them, in contrast
to a digital computer that assembles thoughts and
feelings from bits of data. This new understanding of
how the brain functions has challenged several
longstanding assumptions about the nature of emo-
tions. While it was formerly maintained that emo-
tions originated only in the brain, we now recognize
that emotions can be more accurately described as a
product of the brain and body acting in concert.
Moreover, evidence suggests that of the bodily or-
gans, the heart may play a particularly important
role in emotional experience. Research in the rela-
tively new discipline of neurocardiology has con-
firmed that the heart is a sensory organ and acts as a
sophisticated information encoding and processing
center that enables it to learn, remember, and make
independent functional decisions that do not involve
the cerebral cortex.9 Additionally, numerous experi-
ments have demonstrated that patterns of cardiac
afferent neurological input to the brain not only af-
fect autonomic regulatory centers, but also influence
higher brain centers involved in perception and emo-
tional processing.10-13
Heart rate variability (HRV), derived from the
ECG, is a measure of the naturally occurring beat-
to-beat changes in heart rate that has proven to be
invaluable in studying the physiology of emotions.
The analysis of HRV, or heart rhythms, provides a
powerful, noninvasive measure of neurocardiac func-
tion that reflects heart-brain interactions and auto-
nomic nervous system dynamics, which are particu-
larly sensitive to changes in emotional states.
14, 15
Our
research, along with that of others, suggests that there
is an important link between emotions and changes
in the patterns of both efferent (descending) and af-
ferent (ascending) autonomic activity.
12, 14, 16-18
These
changes in autonomic activity are associated with
dramatic changes in the pattern of the heart’s rhythm
that often occur without any change in the amount
of heart rate variability. Specifically, we have found
that during the experience of negative emotions such
as anger, frustration, or anxiety, heart rhythms be-
come more erratic and disordered, indicating less
synchronization in the reciprocal action that ensues
between the parasympathetic and sympathetic
branches of the autonomic nervous system (ANS).
14,
16
In contrast, sustained positive emotions, such as
appreciation, love, or compassion, are associated with
highly ordered or coherent patterns in the heart
rhythms, reflecting greater synchronization between
the two branches of the ANS, and a shift in autonomic
balance toward increased parasympathetic activity
14,
16, 17, 19
(Figure 3).
Physiological Coherence
Based on these findings, we have introduced
the term physiological coherence to describe a num-
ber of related physiological phenomena associated

Real-time heart rate variability (heart rhythm) pattern of an
individual making an intentional shift from a self-induced state
of frustration to a genuine feeling of appreciation by using a
positive emotion refocusing exercise known as the Freeze-
Frame technique. It is of note that when the recording is
analyzed statistically, the
amount
of heart rate variability is
found to remain virtually the same during the two different
emotional states; however, the
pattern
of the heart rhythm
changes distinctly. Note the immediate shift from an erratic,
disordered heart rhythm pattern associated with frustration to
a smooth, harmonious, sine wave-like (coherent) pattern as
the individual uses the positive emotion refocusing technique
and self-generates a heartfelt feeling of appreciation.

with more ordered and harmonious interactions
among the body’s systems.20
The term coherence has several related defi-
nitions. A common definition of the term is “the
quality of being logically integrated, consistent, and
intelligible,” as in a coherent argument. In this con-
text, thoughts and emotional states can be consid-
ered “coherent” or “incoherent.” Importantly, how-
ever, these associations are not merely metaphori-
cal, as different emotions are in fact associated with
different degrees of coherence in the oscillatory
rhythms generated by the body’s various systems.
The term “coherence” is used in physics to
describe the ordered or constructive distribution of
power within a waveform. The more stable the fre-
quency and shape of the waveform, the higher the
coherence. An example of a coherent wave is the
sine wave. The term autocoherence is used to de-
note this kind of coherence. In physiological systems,
this type of coherence describes the degree of order
and stability in the rhythmic activity generated by a
single oscillatory system. Methodology for comput-
ing coherence has been published elsewhere.14
Coherence also describes two or more waves
that are either phase- or frequency-locked. In physi-
ology, coherence is used to describe a functional
mode in which two or more of the body’s oscillatory
systems, such as respiration and heart rhythms, be-
come entrained and oscillate at the same frequency.
The term cross-coherence is used to specify this type
of coherence.
All the above definitions apply to the study of
both emotional physiology and bioelectromagnetism.
We have found that positive emotions are associated
with a higher degree of coherence within the heart’s
rhythmic activity (autocoherence) as well as in-
creased coherence between different oscillatory sys-
tems (cross-coherence/entrainment).14, 20 Typically,
entrainment is observed between heart rhythms,
respiratory rhythms, and blood pressure oscillations;
however, other biological oscillators, including very
low frequency brain rhythms, craniosacral rhythms,
electrical potentials measured across the skin, and,
most likely, rhythms in the digestive system, can also
become entrained.20
We have also demonstrated that physiological
coherence is associated with increased synchroni-
zation between the heartbeat (ECG) and alpha
rhythms in the EEG. In experiments measuring
heartbeat evoked potentials, we found that the brain’s
alpha activity (8-12 hertz frequency range) is natu-
rally synchronized to the cardiac cycle. However,
when subjects used a positive emotion refocusing
technique to consciously self-generate feelings of
appreciation, their heart rhythm coherence signifi-
cantly increased, as did the ratio of the alpha rhythm
that was synchronized to the heart.20, 21
Another related phenomenon associated with
physiological coherence is resonance. In physics,
resonance refers to a phenomenon whereby an un-
usually large vibration is produced in a system in
response to a stimulus whose frequency is identical
or nearly identical to the natural vibratory frequency
of the system. The frequency of the vibration pro-
duced in such a state is said to be the resonant fre-
quency of the system. When the human system is
operating in the coherent mode, increased synchro-
nization occurs between the sympathetic and para-
sympathetic branches of the ANS, and entrainment
between the heart rhythms, respiration and blood
pressure oscillations is observed. This occurs because
these oscillatory subsystems are all vibrating at the
resonant frequency of the system. Most models show
that the resonant frequency of the human cardio-
vascular system is determined by the feedback loops
between the heart and brain.22, 23 In humans and in
many animals, the resonant frequency is approxi-
mately 0.1 hertz, which is equivalent to a 10-second
rhythm.
In summary, we use coherence as an umbrella
term to describe a physiological mode that encom-
passes entrainment, resonance, and synchroniza-
tion—distinct but related phenomena, all of which
emerge from the harmonious activity and interac-
tions of the body’s subsystems. Correlates of physi-
ological coherence include: increased synchroniza-
tion between the two branches of the ANS, a shift in
autonomic balance toward increased parasympa-
thetic activity, increased heart-brain synchroniza-
tion, increased vascular resonance, and entrainment
between diverse physiological oscillatory systems.
The coherent mode is reflected by a smooth, sine
wave-like pattern in the heart rhythms (heart rhythm
coherence) and a narrow-band, high-amplitude peak
in the low frequency range of the heart rate variabil-
ity power spectrum, at a frequency of about 0.1 hertz.

Benefits of Coherence
Coherence confers a number of benefits to the
system in terms of both physiological and psycho-
logical functioning. At the physiological level, there
is increased efficiency in fluid exchange, filtration,
and absorption between the capillaries and tissues;
increased ability of the cardiovascular system to adapt
to circulatory demands; and increased temporal syn-
chronization of cells throughout the body.
24, 25
This
results in increased system-wide energy efficiency and
conservation of metabolic energy. These observations
support the link between positive emotions and in-
creased physiological efficiency that may partially
explain the growing number of documented correla-
tions between positive emotions, improved health,
and increased longevity.
26-28
We have also shown that
practicing certain techniques that increase physiologi-
cal coherence is associated with both short-term and
long-term improvement in several objective health-
related measures, including enhanced humoral im-
munity
29, 30
and an increased DHEA/cortisol ratio.
17
Increased physiological coherence is similarly
associated with psychological benefits, including
improvements in cognitive performance and mental
clarity as well as increased emotional stability and
well-being.20, 31 Studies conducted in diverse popula-
tions have documented significant reductions in
stress and negative affect and increases in positive
mood and attitudes in individuals using coherence-
building techniques.17, 19, 29, 31, 32
Improvements in clinical status, emotional
well-being and quality of life have also been demon-
strated in various medical patient populations in in-
tervention programs using coherence-building ap-
proaches. For example, significant blood pressure
reductions have been demonstrated in individuals
with hypertension;33 improved functional capacity
and reduced depression in congestive heart failure
patients;34 improved psychological health and qual-
ity of life in patients with diabetes;35 and improve-
ments in asthma.36 Another study reported reduc-
tions in pathological symptoms and anxiety and sig-
nificant improvements in positive affect, physical
vitality, and general well-being in individuals with
HIV infection and AIDS.37
Additionally, patient case history data provided
by numerous health care professionals report sub-
stantial improvements in health and psychological
status and frequent reductions in medication require-
ments in patients with such medical conditions as
cardiac arrhythmias, chronic fatigue, environmen-
tal sensitivity, fibromyalgia, and chronic pain.38 Fi-
nally, techniques that increase physiological coher-
ence have been used effectively by mental health
professionals in the treatment of emotional disor-
ders, including anxiety, depression, panic disorder,
and post-traumatic stress disorder.38
Drivers of Physiological Coherence
Although physiological coherence is a natural
state that can occur spontaneously during sleep and
deep relaxation, sustained episodes during normal
daily activities are generally rare. While specific
rhythmic breathing methods can induce coherence
for brief periods, cognitively directed, paced breath-
ing is difficult for many people to maintain. On the
other hand, our findings indicate that individuals can
produce extended periods of physiological coherence
by actively generating and sustaining a feeling of ap-
preciation or other positive emotions. Sincere posi-
tive feelings appear to excite the system at its reso-
nant frequency, allowing the coherent mode to
emerge naturally. This typically makes it easier for
people to sustain a positive emotion for much longer
periods, thus facilitating the process of establishing
and reinforcing coherent patterns in the neural ar-
chitecture as the familiar reference. Once a new pat-
tern is established, the brain strives to maintain a
match with the new program, thus increasing the
probability of maintaining coherence and reducing
stress, even during challenging situations.12
Doc Childre, founder of the Institute of Heart-
Math, has developed a number of practical positive
emotion refocusing and emotional restructuring tech-
niques that allow people to quickly self-generate co-
herence at will.39, 40 Known as the HeartMath system,
these techniques utilize the heart as a point of entry
into the psychophysiological networks that connect
the physiological, mental, and emotional systems.
In essence, because the heart is a primary generator
of rhythmic neural and energetic patterns in the
body—influencing brain processes that control the
ANS, cognitive function and emotion—it provides an
access point from which system-wide dynamics can
be quickly and profoundly affected. Research stud-
ies and the experience of numerous health care pro-

fessionals indicate that HeartMath coherence-build-
ing techniques are easily learned, have a high rate of
compliance, and are highly adaptable to a wide range
of demographic groups.
Promoting Physiological Coherence Through Heart
Rhythm Coherence Feedback Training
Used in conjunction with positive emotion-
based coherence-building techniques, heart rhythm
feedback training can be a powerful tool to assist
people in learning how to self-generate increased
physiological coherence.41 We have developed a por-
table heart rhythm monitoring and feedback system
that enables physiological coherence to be objectively
monitored and quantified. Known as the Freeze-
Framer® coherence-building system (HeartMath
LLC, Boulder Creek, CA), this interactive hardware/
software system monitors and displays individuals’
heart rate variability patterns in real time as they
practice the positive emotion refocusing and emo-
tional restructuring techniques taught in an on-line
tutorial. Using a fingertip sensor to record the pulse
wave, the Freeze-Framer plots changes in heart rate
on a beat-to-beat basis. As people practice the co-
herence-building techniques, they can readily see and
experience the changes in their heart rhythm pat-
terns, which generally become more ordered,
smoother, and more sine wave-like as they experi-
ence positive emotions. This process reinforces the
natural association between the physiological coher-
ence mode and positive feelings. The software also
analyzes the heart rhythm patterns for coherence
level, which is fed back to the user as an accumu-
lated numerical score or success in playing one of
three on-screen games designed to reinforce the co-
herence-building skills. The real-time physiological
feedback essentially takes the guesswork and ran-
domness out of the process of self-inducing a coher-
ent state, resulting in greater consistency, focus, and
effectiveness in shifting to a beneficial psychophysi-
ological mode.
Heart rhythm coherence feedback training has
been successfully used in clinical settings by physi-
cians, mental health professionals and neurofeedback
therapists to facilitate health improvements in pa-
tients with numerous physical and psychological dis-
orders. It is also increasingly being utilized in corpo-
rate, law enforcement, and educational settings to
enhance physical and emotional health and improve
performance.
Heart Rhythms and Bioelectromagnetism
The first biomagnetic signal was demonstrated
in 1963 by Gerhard Baule and Richard McFee in a
magnetocardiogram (MCG) that used magnetic in-
duction coils to detect fields generated by the hu-
man heart.42 A remarkable increase in the sensitiv-
ity of biomagnetic measurements was achieved with
the introduction of the Superconducting Quantum
Interference Device (SQUID) in the early 1970s, and
the ECG and MCG have since been shown to closely
parallel one another.43
The heart generates a series of electromagnetic
pulses in which the time interval between each beat
varies in a complex manner. These pulsing waves of
electromagnetic energy create fields within fields and
give rise to interference patterns when they interact
with magnetically polarizable tissues and substances.
Figure 4 shows two different power spectra
derived from an average of 12 individual 10-second
epochs of ECG data recorded during differing psy-
chophysiological modes. The plot on the left was
produced while the subject was in a state of deep
appreciation, whereas the plot on the right was gen-
erated while the subject experienced recalled feel-
ings of anger. The difference in the patterns, and thus
the information they contain, can be clearly seen.
There is a direct correlation between the patterns in
the heart rate variability rhythm and the frequency
patterns in the spectrum of the ECG or MCG. Ex-
periments such as these indicate that psychophysi-
ological information can be encoded into the elec-
tromagnetic fields produced by the heart.14, 44
Bioelectromagnetic Communication Between People
The human body is replete with mechanisms
for detecting its external environment. Sense organs,
the most obvious example, are specifically geared to
react to touch, temperature, select ranges of light and
sound waves, etc. These organs are acutely sensitive
to external stimuli. The nose, for example, can de-
tect one molecule of gas, while a cell in the retina of
the eye can detect a single photon of light; and if the
ear were any more sensitive, it would pick up the
sound of the random vibrations of its own molecules.

The interaction between two human beings—
for example, the consultation between a patient and
her clinician—is a very sophisticated dance that in-
volves many subtle factors. Most people tend to think
of communication solely in terms of overt signals
expressed through facial movements, voice qualities,
gestures and body movements. However, evidence
now supports the perspective that a subtle yet influ-
ential electromagnetic or “energetic” communica-
tion system operates just below our conscious level
of awareness. The following section will discuss data
suggesting that this energetic system contributes to
the “magnetic” attractions or repulsions that occur
between individuals. It is also quite possible that
these energetic interactions can affect the therapeu-
tic process.
The concept of energy or information exchange
between individuals is central to many of the East-
ern healing arts, but its acceptance in Western medi-
cine has been hampered by the lack of a plausible
mechanism to explain the nature of this “energy in-
formation” or how it is communicated. However,
numerous studies investigating the effects of heal-
ers, Therapeutic Touch practitioners, and other in-
dividuals have demonstrated a wide range of signifi-
cant effects including the influence of “energetic”
approaches on wound healing rates,46, 47 pain,48, 49
hemoglobin levels,50 conformational changes of DNA
and water structure,51-52 as well as psychological
states.53 Although these reports show beneficial re-
sults, they have been largely ignored because of the
lack of any scientific rationale to explain how the
effects are achieved.
Physiological Linkage and Empathy
The ability to sense what other people are feel-
ing is an important factor in allowing us to connect
or communicate effectively with others. The smooth-
ness or flow in any social interaction depends to a
great extent on the establishment of a spontaneous
entrainment or linkage between individuals. When
people are engaged in deep conversation, they begin
to fall into a subtle dance, synchronizing their move-
ments and postures, vocal pitch, speaking rates, and
length of pauses between responses,54 and, as we are
now discovering, important aspects of their physiol-
ogy can also become linked and entrained.
Several studies have investigated different
types of physiological synchronization or entrain-
ment between individuals during empathetic mo-
ments or between clinician and patient during thera-
peutic sessions. One study by Levenson and Gottman
at the University of California at Berkeley looked at
Figure 4. ECG spectra during different emotional states.
The above graphs are the average power spectra of 12 individual 10-second epochs of ECG data, which reflect information patterns
contained in the electromagnetic field radiated by the heart. The lefthand graph is an example of a spectrum obtained during a period
of high heart rhythm coherence generated during a sustained heartfelt experience of appreciation. The graph on the right depicts a
spectrum associated with a disordered heart rhythm generated during feelings of anger.

physiological synchronization in married couples
during empathetic interactions. Researchers exam-
ined couples’ physiological responses during two dis-
cussions: a neutral “How was your day?” conversa-
tion, to establish a baseline, and a second conversa-
tion containing more emotional content in which the
couples were asked to spend fifteen minutes discuss-
ing something about which they disagreed. After the
disagreement, one partner was asked to leave the
room while the other stayed to watch a replay of the
talk and identify portions of the dialogue where he
or she was actually empathizing but did not express
it. Both spouses individually engaged in this proce-
dure. Levenson was then able to identify those seg-
ments of the video where empathy occurred and
match the empathetic response to physiological re-
sponses in both partners. He found that in partners
who were adept at empathizing, their physiology
mimicked their partner’s while they empathized. If
the heart rate of one went up, so did the heart rate
of the other; if the heart rate slowed, so did that of
the empathic spouse.55 Other studies observing the
psychophysiology of married couples while interact-
ing were able to predict the probability of divorce.56
Although studies that have examined physi-
ological linkages between therapists and patients
have suffered from methodological challenges, they
do support a tendency to autonomic attunement
during periods of empathy between the therapist and
patient.57 Dana Redington, a psychophysiologist at
the University of California, San Francisco, analyzed
heart rate variability patterns during therapist-pa-
tient interactions using a nonlinear dynamics ap-
proach. Redington and colleagues used phase space
maps to plot changes in the beat-to-beat heart rate
of both the therapist and patient during psycho-
therapy sessions. They found that the trajectories in
the therapist’s patterns often coincided with the
patient’s during moments when the therapist expe-
rienced strong feelings of empathy for the patient.58
Carl Marci at Harvard University found evidence of
a more direct linkage between patients and thera-
pists using skin conductance measures. During ses-
sions of psychodynamic psychotherapy, Marci ob-
served a quantifiable fluctuation and entrainment in
the pattern of physiological linkage within patient-
therapist dyads, which was related to patient per-
ception of the therapist’s empathy. In addition, the
preliminary results of his studies indicate that dur-
ing periods of low physiological linkage there are
fewer empathetic comments, more incidents of in-
correct interpretations, less shared affect, and fewer
shared behavioral responses when compared to epi-
sodes of high physiological linkage.59
Cardioelectromagnetic Communication
An important step in testing our hypothesis
that the heart’s electromagnetic field could transmit
signals between people was to determine if the field
and the information modulated within it could be
detected by other individuals.
In conducting these experiments, the question
being asked was straightforward. Namely, can the
electromagnetic field generated by the heart of one
individual be detected in physiologically relevant
ways in another person, and if so does it have any
discernible biological effects? To investigate these
possibilities, we used signal-averaging techniques to
detect signals that were synchronous with the peak
of the R-wave of one subject’s ECG in recordings of
another subject’s electroencephalogram (EEG) or
brain waves. My colleagues and I have performed
numerous experiments in our laboratory over a pe-
riod of several years using these techniques,60 and
several examples are included below to illustrate
some of these findings. In the majority of these ex-
periments, subjects were seated in comfortable, high-
back chairs to minimize postural changes with the
positive ECG electrode located on the side at the
left sixth rib and referenced to the right supraclav-
icular fossa according to the International 10-20 sys-
tem. The ECG and EEG were recorded from both
subjects simultaneously so that the data (typically
sampled at 256 hertz or higher) could be analyzed
for simultaneous signal detection in both.
To clarify the direction in which the signal flow
was analyzed, the subject whose ECG R-wave was
used as the time reference for the signal averaging
procedure is referred to as the “signal source,” or
simply “source.” The subject whose EEG was ana-
lyzed for the registration of the source’s ECG signal
is referred to as the “signal receiver,” or simply “re-
ceiver.” The number of averages used in the major-
ity of the experiments was 250 ECG cycles (~ 4 min-
utes). The subjects did not consciously intend to send
or receive a signal and, in most cases, were unaware
of the true purpose of the experiments. The results

of these experiments have led us to conclude that
the nervous system acts as an antenna, which is tuned
to and responds to the magnetic fields produced by
the hearts of other individuals. My colleagues and I
call this energetic information exchange
cardioelectromagnetic communication and believe
it to be an innate ability that heightens awareness
and mediates important aspects of true empathy and
sensitivity to others. Furthermore, we have observed
that this energetic communication ability can be
enhanced, resulting in a much deeper level of non-
verbal communication, understanding, and connec-
tion between people. We also propose that this type
of energetic communication between individuals may
play a role in therapeutic interactions between cli-
nicians and patients that has the potential to pro-
mote the healing process.
From an electrophysiological perspective, it
appears that sensitivity to this form of energetic com-
munication between individuals is related to the abil-
ity to be emotionally and physiologically coherent.
The data indicate that when individuals are in the
coherent mode, they are more sensitive to receiving
information contained in the fields generated by oth-
ers. In addition, during physiological coherence, in-
ternal systems are more stable, function more effi-
ciently, and radiate electromagnetic fields contain-
ing a more coherent structure.14
The Electricity of Touch
The first step was to determine if the ECG sig-
nal of one person could be detected in another
individual’s EEG during physical contact. For these
experiments we seated pairs of subjects 4 feet apart,
during which time they were simultaneously moni-
tored. An initial 10-minute baseline period (no physi-
cal contact) was followed by a 5-minute period in
which subjects remained seated but reached out and
held the hand of the other person (like shaking hands).
Figure 5 shows a typical example of the results.
Prior to holding hands, there was no indication
that Subject 1’s ECG signals were detected in Subject
2’s EEG. However, upon holding hands, Subject 1’s
ECG could be clearly detected in Subject 2’s EEG at
all monitored locations. While in most pairs a clear

signal transfer between the two subjects was measur-
able in one direction, it was only observed in both
directions simultaneously in about 30 percent of the
pairs (i.e., Subject 2’s ECG could be detected in Sub-
ject 1’s EEG at the same time that Subject 1’s ECG
was detectable in Subject 2’s EEG). From other ex-
periments we have concluded that this phenomenon
is not related to gender or amplitude of the ECG sig-
nal. As shown later, an important variable appears to
be the degree of physiological coherence maintained.
After demonstrating that the ECG from one
individual could be detected in another’s EEG dur-
ing physical contact, we completed a series of ex-
periments to determine if the signal was transferred
via electrical conduction through the skin alone or
if it was also radiated. In one set of experiments sub-
jects were recorded holding hands under two sets of
conditions: barehanded and wearing form-fitting,
latex lab gloves. The ECG signal of one subject could
be clearly detected in the EEG of the other subject
even when they were wearing the gloves; however,
the signal amplitude was reduced approximately ten-
fold. This suggests that while a significant degree of
the signal transfer occurs through skin conduction,
the signal is also radiated or capacitively coupled
between individuals. When conductive gel was used
to decrease skin-to-skin contact resistance, the sig-
nal amplitude was unaffected. For additional detail,
the protocols and data from these and related ex-
periments are described elsewhere.60
We also conducted several experiments to de-
termine if the transfer of cardiac energy and infor-
mation is affected by the orientation of the subjects’
hand-holding (i.e., source’s left hand holding
receiver’s right hand vs. source’s right hand holding
receiver’s left hand, etc.). The subjects were in-
structed to hold hands in each of the four possible
orientations for 5 minutes. Since we only performed
this experiment with three subject pairs, the results
should be interpreted with a degree of caution; how-
ever, we did find that consistent and measurable dif-
ferences could be observed. The source’s ECG ap-
peared with the largest amplitude in the receiver’s
EEG when the receiver’s right hand was held by ei-
ther the source’s left or right hand. When the
receiver’s left hand was held by the source’s right
hand, the signal appeared at a lower amplitude. Fi-
nally, when the receiver’s left hand was held by the
source’s left hand, the ECG signal was either very
low in amplitude or undetectable.60
The possibility exists that in some cases the sig-
nal appearing in the receiving subject’s recordings could
be the receiver’s own ECG rather than that of the other
subject. Given the signal averaging procedure em-
ployed, this could only occur if the source’s ECG was
continually and precisely synchronized with the
receiver’s ECG. To definitively rule this out, the data
in all experiments were checked for this possibility.
Simultaneously and independently, Russek and
Schwartz at the University of Arizona conducted
similar experiments in which they were also able to
demonstrate the detection of an individual’s cardiac
signal in another’s EEG recording in two people sit-
ting quietly, without physical contact.61 In a publica-
tion entitled “Energy Cardiology,” they discuss the
implications of their findings in the context of what
they call a “dynamical energy systems approach”
describing the heart as a prime generator, organizer,
and integrator of energy in the human body.62
Heart-Brain Synchronization During Nonphysical
Contact
Since the magnetic component of the field pro-
duced by the heartbeat is radiated outside the body
and can be detected several feet away with SQUID-
based magnetometers,
1
we further tested the trans-
ference of signals between subjects who were not in
physical contact. In these experiments, the subjects
were either seated side by side or facing each other at
varying distances. In some cases, we were able to de-
tect a clear QRS-shaped signal in the receiver’s EEG,
but not in others. Although the ability to obtain a clear
registration of the ECG in the other person’s EEG
declined as the distance between subjects was in-
creased, the phenomenon appears to be nonlinear. For
instance, a clear signal could be detected at a distance
of 18 inches in one session but was undetectable in
the very next trial at a distance of only 6 inches. Al-
though transmission of a clear QRS-shaped signal is
uncommon at distances over 6 inches in our experi-
ence, this does not preclude the possibility that physi-
ologically relevant information can be communicated
between people at longer distances.
Because of the apparent nonlinear nature of
the phenomenon and the growing body of data sug-
gesting that the detection of weak periodic signals
can be enhanced in biological systems via a mecha-
© Copyright 2003 Institute of HeartMath
11
nism known as stochastic resonance, we investigated
the possibility that physiological coherence may be
an important variable in determining whether the
cardiac fields are detected past the 6-inch distance.
The nonlinear stochastic resonance model predicts
that under certain circumstances, very weak coher-
ent electromagnetic signals are detectable by biologi-
cal systems and can have significant biological ef-
fects.63-66 Stochastic resonance will be discussed in
more detail in a subsequent section.
Figure 6 shows the data from two subjects
seated facing one another at a distance of 5 feet, with
no physical contact. The subjects were asked to use
the Heart Lock-In technique,39, 40 an emotional re-
structuring exercise that has been demonstrated to
produce sustained states of physiological coherence
when properly applied.17 There was no intention to
“send energy” and participants were not aware of
the purpose of the experiment. The top three traces
show the signal-averaged waveforms derived from
the EEG locations along the medial line of the head.
Note that in this example, the signal averaged
waveforms do not contain any semblance of the QRS
complex shape as seen in the physical contact ex-
periments; rather they reveal the occurrence of an
alpha wave synchronization in the EEG of one sub-
ject that is precisely timed to the R-wave of the other
subject’s ECG. Power spectrum analysis of the sig-
nal averaged EEG waveforms was used to verify that
it is the alpha rhythm that is synchronized to the
other person’s heart. This alpha synchronization does
not imply that there is increased alpha activity, but
it does show that the existing alpha rhythm is able
to synchronize to extremely weak external electro-
magnetic fields such as those produced by another
person’s heart. It is well known that the alpha rhythm
can synchronize to an external stimulus such as
sound or light flashes, but the ability to synchronize
to such a subtle electromagnetic signal is surprising.
As mentioned, there is also a significant ratio of al-
pha activity that is synchronized to one’s own heart-
beat, and the amount of this synchronized alpha ac-
tivity is significantly increased during periods of
physiological coherence.20, 21
Figure 7 shows an overlay plot of one of Sub-
ject 2’s signal averaged EEG traces and Subject 1’s
signal averaged ECG. This view shows an amazing
degree of synchronization between the EEG of Sub-
ject 2 and Subject 1’s heart. These data show that it
is possible for the magnetic signals radiated by the
heart of one individual to influence the brain rhythms
of another. In addition, this phenomenon can occur
at conversational distances. As yet, we have not
tested this effect at distances greater than 5 feet.
Figure 6. Heart-brain synchronization between two people.
The top three traces are Subject 2’s signal averaged EEG
waveforms, which are synchronized to the R-wave of Subject
1’s ECG. The lower plot shows Subject 2’s heart rate variability
pattern, which was coherent throughout the majority of the
record. The two subjects were seated at a conversational distance
without physical contact.

This graph is an overlay plot of the same EEG and ECG data
shown in Figure 6. Note the similarity of the wave shapes,
indicating a high degree of synchronization.

Figure 8 shows the data from the same two
subjects during the same time period, only it is ana-
lyzed for alpha synchronization in the opposite di-
rection (Subject 1’s EEG and Subject 2’s ECG). In
this case, we see that there is no observable syn-
chronization between Subject 1’s EEG and Subject
2’s ECG. The key difference between the data shown
in Figure 6 and Figure 8 is the high degree of physi-
ological coherence maintained by Subject 2. In other
words, the degree of coherence in the receiver’s heart
rhythms appears to determine whether his/her brain
waves synchronize to the other person’s heart.
This suggests that when one is in a physiologi-
cally coherent mode, one exhibits greater sensitiv-
ity in registering the electromagnetic signals and in-
formation patterns encoded in the fields radiated by
the hearts of other people. At first glance these data
may be mistakenly interpreted as suggesting that we
are more vulnerable to the potential negative influ-
ence of incoherent patterns radiated by those around
us. In fact, the opposite is true, because when people
are able to maintain the physiological coherence
mode, they are more internally stable and thus less
vulnerable to being negatively affected by the fields
emanating from others. It appears that it is the in-
creased internal stability and coherence that allows
for the increased sensitivity to emerge.
This fits quite well with our experience in train-
ing thousands of individuals in how to self-generate
and maintain coherence while they are listening to
others during conversation. Once individuals learn
this skill, it is a common experience that they be-
come much more attuned to other people and are
able to detect and understand the deeper meaning
behind spoken words. They are often able to sense
what someone else really wishes to communicate
even when the other person may not be clear about
that which he is attempting to say. This technique,
called Intuitive Listening, helps people to feel fully
heard and promotes greater rapport and empathy
between people.67
Our data are also relevant to Russek and
Schwartz’s findings that people who are more accus-
tomed to experiencing positive emotions such as love
and care are better receivers of cardiac signals from
others.61 In their follow-up study of 20 college stu-
dents, those who had rated themselves as having been
raised by loving parents exhibited significantly
greater registration of an experimenter’s ECG in their
EEG than others who had perceived their parents as
less loving. Our findings, which show that positive
emotions such as love, care, and appreciation are
associated with increased physiological coherence,
suggest the possibility that the subjects in Russek
and Schwartz’s study had higher ratios of physiologi-
cal coherence, which could explain the greater reg-
istration of cardiac signals.
Heart Rhythm Entrainment Between Subjects
When heart rhythms are more coherent, the
electromagnetic field that is radiated outside the body
correspondingly becomes more organized, as shown
in Figure 4. The data presented thus far indicate that
signals and information can be communicated ener-
getically between individuals, but so far have not
implied a literal entrainment of two individuals’ heart
rhythm patterns. We have found that entrainment
of heart rhythm patterns between individuals is pos-
sible, but usually occurs only under very specific
conditions. In our experience, true heart rhythm
entrainment between individuals is very rare during
Figure 8.

normal waking states. We have found that individu-
als who have a close living or working relationship
are the best candidates for exhibiting this type of
entrainment. Figure 9 shows an example of heart
rhythm entrainment between two women who have
a close working relationship and practice coherence-
building techniques regularly. For this experiment,
they were seated 4 feet apart, and, although blind to
the data, were consciously focused on generating feel-
ings of appreciation for each other.
A more complex type of entrainment can also
occur during sleep. Although we have only looked at
couples who are in long-term stable and loving rela-
tionships, we have been surprised at the high degree
of heart rhythm synchrony observed in these couples
while they sleep. Figure 10 shows an example of a
small segment of data from one couple. These data
were recorded using an ambulatory ECG (Holter)
recorder with a modified cable harness that allowed
the concurrent recording of two individuals on the
same tape. Note how the heart rhythms simulta-
neously change in the same direction and how heart
rates converge. Throughout the recording, clear tran-
sition periods are evident in which the heart rhythms
move into greater synchronicity, maintain the en-
trainment for some time, and then drift out again.
This implies that unlike in most wakeful states, en-
trainment between the heart rhythms of individuals
can and does occur during sleep.
We have also found that a type of heart rhythm
entrainment or synchronization can occur in inter-
actions between people and their pets. Figure 10
shows the results of an experiment looking at the
heart rhythms of my son Josh (15 years old at the
time of the recording) and his dog, Mabel. Here we
used two Holter recorders, one fitted on Mabel and
the other on Josh. We synchronized the recorders
and placed Mabel in one of our labs. Josh then en-
tered the room and sat down and proceeded to con-
sciously feel feelings of love towards Mabel. Note the
synchronous shift to increased coherence in the heart
rhythms of both Josh and Mabel as Josh consciously
feels love for his pet.

Influence of the Heart’s Bioelectromagnetic Field on
Cells
The idea that information can be communi-
cated between biological systems and cause an effect
in another living system is far from a new concept.
This phenomenon has been examined in many dif-
ferent biological systems. A review of this literature
is beyond the scope of this paper, but the subject has
been reviewed recently by Marilyn Schlitz, Director
of Research at the Institute of Noetic Sciences. In
her review, both intention and how it is focused (i.e.,
attitude) are considered important variables in affect-
ing outcomes.
68
Further, studies conducted in our
laboratory suggest that emotional state and the de-
gree of coherence in the electromagnetic fields pro-
duced by the heart are also important variables.
We have long suspected that one aspect of the
heart’s electromagnetic field acts as a carrier wave
for information that can affect the function of cells
in our own body as well as other biological systems
in proximity. In the early 1990s, we undertook a se-
ries of experiments to test this hypothesis. This
project evolved over several years and extended into
many types of experiments. We were able to demon-
strate that individuals can cause changes in the struc-
ture of water,
51
in cell growth rate, and in the confor-
mational state of DNA.
52
In general, we found that in
order to produce these effects in a reliable manner,
both a high degree of heart rhythm coherence and
an intention to produce a given change were critical.
Much scientific research has attempted to de-
termine the effects, if any, of electromagnetic fields
(particularly the 50 and 60-hertz fields generated by
power lines) on cells, and has yielded largely incon-
clusive results. However, comparatively little effort
has been made to understand the effects of the body’s
Figure 11. Heart rhythm patterns of a boy and his dog.
These data were obtained using ambulatory ECG (Holter) recorders fitted on both Josh, a boy, and Mabel, his pet dog. When Josh entered
the room where Mabel was waiting and consciously felt feelings of love and care towards his pet, his heart rhythms became more
coherent, and this change appears to have influenced Mabel heart rhythms, which then also became more coherent. When Josh left the
room, Mabel’s heart rhythms became much more chaotic and incoherent, suggesting separation anxiety!

endogenous fields, those that actually comprise the
bioelectromagnetic environment in which our cells
are continuously bathed. The most consistent and
strongest source of an endogenous electromagnetic
field is of course the heart.
In order to test the hypothesis that the elec-
tromagnetic field generated by the heart may have
direct effects at the cellular level, we performed a
series of cell culture experiments in which we ex-
posed several different cell lines to simulated heart
fields. To do this, we first acquired ECG data at a 10-
kilohertz sample rate from people in various emo-
tional states, generating correspondingly different
heart rhythm patterns. We then used a digital-to-
analog converter to recreate these ECG signals,
which were fed into a specially built amplifier that
could accurately recreate the low frequency portions
of the ECG along with the higher frequencies. The
output of the amplifier was used to drive a coil in
which cell cultures were placed. For the experiment
described here, a 2-inch diameter solenoid coil 15
inches high was placed vertically inside a 5% carbon
dioxide incubator. Human fibroblasts (skin cells)
were placed in 35-millimeter petri dishes inside the
center section of the coils where the field was uni-
form. Typically, 10 individual petri dishes, each con-
taining the same number of cells, were placed inside
the coils. Identical cells were placed in a mock coil
in a separate incubator and served as controls for
each experiment. The field strength to which the cells
in the human body are exposed from a normal heart-
beat was determined. The output of the amplifier
was adjusted so that the cells placed in the coil were
exposed to approximately the same field strength as
they would be in the body. While the cells were grow-
ing in the incubator over a 6-day period, they were
continuously exposed to the ECG signals.
After exposure, the growth rates of the cells in
the active and control coils were measured using a
colorimetric staining assay. After many trials and
variations of this basic experiment, we found that fi-
broblast cells exposed to the heart’s field exhibited a
mean increase in growth rate of 20% as compared to
the controls. We also performed several trials in which
we exposed the same type cells to a 60-hertz field of
the same average magnitude of the heart’s field. In
this case, there was no significant change in the growth
rate when compared to the controls. We did find a
slight difference in the growth rate in cells exposed to
coherent versus incoherent ECG signals. The coher-
ent field yielded a higher growth rate; however, this
effect did not reach statistical significance in this set
of experiments. Thus, it appears that the presence or
absence of a cardiac field was the primary variable to
influence growth rate in these experiments.
One particularly intriguing experiment was
performed in which healthy human fibroblasts and
human fibrosarcoma cells (tumor cells from the same
lineage) were both exposed to the same coherent
ECG signal. We found that the growth of the healthy
cells was facilitated by 20%, as expected, while the
growth of the tumor cells was inhibited by 20%.
These results may relate to work conducted in Ger-
many by Ulrich Randoll with cancer patients. He has
found that by monitoring a patient’s own heartbeat
and using it to trigger the application of an exter-
nally applied pulsed field, he has been able to suc-
cessfully treat a number of patients with advanced
carcinomas.69 Dr. Randoll’s therapeutic goal is to “re-
generate and stabilize the basic autonomic rhythm
of the organism.” He has also used ultrastructural
tomographic images of living cells to visualize tem-
poral rhythms in the structural elements at the sub-
cellular level. This technique shows clear differences
in the temporal rhythms of cancer cells as compared
to normal cells.70 He is convinced that his treatments
are helping to restore the normal pattern of activity
at the cellular level, which facilitates recovery from
disease, and believes that the rhythm of the heart
and the field it produces are the key to this healing
process.
Mechanisms of Weak Electromagnetic Field Effects in
Biological Systems
A biological response to an external field (sig-
nal) implies that the signal has caused changes in
the system greater than those caused by random fluc-
tuating events, or noise. Theoretical estimates of the
limitations on the detection of very small signals by
sensory systems imposed by the presence of ther-
mal noise (thermal noise limit) were traditionally
made using linear approximation under the assump-
tion that the system is in a state of equilibrium.71
Traditional linear theory predicted that weak, ex-
tremely low frequency electromagnetic fields, such
as that radiated from the human heart, could not
generate enough energy to overcome the thermal
© Copyright 2003 Institute of HeartMath
16
noise limit and thus affect biological systems. How-
ever, more recently it has been recognized that a
linear and equilibrium approach is not appropriate
for modeling biological systems, which are intrinsi-
cally nonlinear, nonequilibrium, and noisy. A num-
ber of experiments have revealed cellular responses
to electromagnetic field magnitudes far smaller than
the theoretical estimates arrived at by linear model-
ing for the minimum field strength required to over-
come the thermal noise limit in these systems.72
It has been proposed that this discrepancy can
in part be accounted for by biological cells’ capacity
to rectify and essentially signal average weak oscil-
lating electromagnetic fields through field-induced
variation in the catalytic activity of membrane-asso-
ciated enzymes or in the conformation of membrane
channel proteins.66, 72 In addition to signal averaging
by the cells, it has also been established that the noise
in biological systems can play a constructive role in
the detection of weak periodic signals via a mecha-
nism known as stochastic resonance.63-66 Stochasm
is a Greek word that describes a system that is ran-
dom but purposeful. In essence, stochastic resonance
is a nonlinear cooperative effect in which a weak,
normally sub-threshold periodic (coherent) stimu-
lus entrains ambient noise, resulting in the periodic
signal becoming greatly enhanced and able to pro-
duce large-scale effects. The signature of stochastic
resonance is noted by the signal-to-noise ratio in the
system rising to a maximum at some optimal noise
intensity, corresponding to the maximum coopera-
tion between the signal and the noise. Essentially,
the noise acts to boost a coherent, sub-threshold sig-
nal to a level above the threshold value, enabling it
to generate measurable effects. Stochastic resonance
is now known to occur in a wide range of biological
systems and processes, including sensory transduc-
tion, neural signal processing, oscillating chemical
reactions,63, 64 and intracellular calcium signaling.73
In addition, coherent electromagnetic fields have
been shown to produce substantially greater effects
than incoherent signals on enzymatic pathways, such
as the ornithine decarboxylase pathway.74 Remark-
ably, experimental studies have documented effects
of subthermal, coherent signals in different biologi-
cal systems for signal amplitudes as small a one-tenth
or even one-hundredth the amplitude of the random
noise component.75-77 As a weak signal becomes more
coherent, the greater its capacity becomes to entrain
ambient noise and thus produce significant effects.
Thus, cellular signal averaging and nonlinear
stochastic resonance provide potential mechanisms
by which increased heart rhythm coherence may pro-
duce significant biological effects, both within and
between people. For example, through such mecha-
nisms, the consistent self-induction of sustained states
of physiological coherence by an individual may give
rise to changes at the cellular level that may enhance
health and healing. Alternatively, a clinician’s coher-
ent cardiac field, which is detected by a patient, may
be amplified in such a way as to positively affect the
patient’s physiology. The importance of signal coher-
ence in this model also suggests that further atten-
tion be given to the contribution of heartfelt positive
emotions and attitudes, as drivers of coherence, in
the healing process. It is possible that the generation
of physiological coherence and biological effects pro-
duced by this beneficial mode may in part explain
the observed relationship between positive emotions
and favorable health outcomes, as well as the em-
phasis that many therapeutic practices place on the
development of a mutually caring relationship be-
tween practitioner and patient.
60
Furthermore, it is
likely that the therapeutic value of interventions that
facilitate the generation and maintenance of sustained
feelings of appreciation, care, and love may derive in
part from bioelectromagnetically-mediated effects on
cellular physiology.
Conclusions and Implications for Clinical Practice
Bioelectromagnetic communication is a real
phenomenon that has numerous implications for
physical, mental, and emotional health. This paper
has focused on the proposition that increasing the
coherence within and between the body’s endogenous
bioelectromagnetic systems can increase physiologi-
cal and metabolic energy efficiency, promote men-
tal and emotional stability, and provide a variety of
health rewards. It is further proposed that many of
the benefits of increased physiological coherence will
ultimately prove to be mediated by processes and
interactions occurring at the electromagnetic or en-
ergetic level of the organism.
With the many physiological and psychologi-
cal benefits that increased coherence appears to of-
fer, helping patients learn to self-generate and sus-
tain this psychophysiological mode with increased

17
consistency in their day-to-day lives provides a new
strategy for clinicians to assist their patients on
multiple levels. There are several straightforward
ways to help patients increase their physiological
coherence. Teaching and guiding them in the prac-
tice of positive emotion refocusing and emotional
restructuring techniques in conjunction with heart
rhythm feedback has proved to be a simple and cost-
effective approach to improving patient outcomes.
These coherence-building methods are not only ef-
fective therapeutic tools in and of themselves, but
by increasing synchronization and harmony among
the body’s internal systems, may also help increase
a patient’s physiological receptivity to the therapeu-
tic effects of other treatments.
Coherence-building approaches may also help
health care practitioners increase their effectiveness
in working with patients. In self-generating a state
of physiological coherence, the clinician has the po-
tential to facilitate the healing process by establish-
ing a coherent pattern in the subtle electromagnetic
environment to which patients are exposed. Since
even very weak coherent signals have been found to
give rise to significant effects in biological systems,
it is possible that such coherent heart fields may pro-
vide unsuspected therapeutic benefits. Furthermore,
by increasing coherence, clinicians may not only
enhance their own mental acuity and emotional sta-
bility, but may also develop increased sensitivity to
subtle electromagnetic information in their environ-
ment. This, in turn, could potentially enable a deeper
intuitive connection and communication between
practitioner and patient, which can be a crucial com-
ponent of the healing process.
In conclusion, I believe that the electromag-
netic energy generated by the heart is an untapped
resource within the human system awaiting further
exploration and application. Acting as a synchroniz-
ing force within the body, a key carrier of emotional
information, and an apparent mediator of a type of
subtle electromagnetic communication between
people, the cardiac bioelectromagnetic field may have
much to teach us about the inner dynamics of health
and disease as well as our interactions with others.
