Video: HearthMath Inner Balance Heart Rate Variability Sensor for iOS - How It Works
Take Charge of How You Feel
It can be easy to feel overwhelmed, anxious and scattered. HeartMath Inner Balance™ sensor for Android and iPhone trains you to shift and replace emotional stress with emotional balance and coherence.
HeartMath Inner Balance uses biohacking technology to analyze and display our heart rhythm, measured by Heart Rate Variability (HRV), which indicates how emotional states are affecting our nervous system. HRV offers a unique window into the quality of communication between the heart and brain, which directly impacts how we feel and perform.
HeartMath Inner Balance technology trains us to self-generate a highly efficient physiological state called HRV Coherence, which helps us increase emotional composure and clearer reasoning. Recommended by health professionals worldwide, HRV coherence training has been associated with many health and performance benefits. A few minutes of daily coherence practice has been shown to reduce and prevent the negative effects of stress, such as overwhelm, fatigue and exhaustion, sleep disruption, anxiety and burnout.
HeartMath has been a pioneer in HRV research and self-regulation training for over 25 years. Over 250 independent peer-reviewed studies have been published on HeartMath technologies and methodologies.
Our heart rhythm patterns are the best reflection of our inner state. We can use the Inner Balance to see what's going on inside of us and learn how to shift into a state of balance, self-reliance and renewing feelings, such as appreciation and compassion.

The Science Behind Inner Balance
HeartMath products, tools and techniques are based on over 25 years of scientific research conducted at the HeartMath Institute on the psychophysiology of stress, emotions, and the interactions between the heart and brain. There are over 300 independent peer-reviewed academic papers published on HeartMath Science.
The Heart-Brain Connection
Most of us have been taught in school that the heart is constantly responding to "orders" sent by the brain in the form of neural signals. However, it is not as commonly known that the heart actually sends more signals to the brain than the brain sends to the heart! Moreover, these heart signals have a significant effect on brain function – influencing emotional processing as well as higher cognitive faculties such as attention, perception, memory, and problem-solving. In other words, not only does the heart respond to the brain, but the brain continuously responds to the heart.
The effect of heart activity on brain function has been researched extensively over about the past 40 years. Earlier research mainly examined the effects of heart activity occurring on a very short time scale - over several consecutive heartbeats at maximum. Scientists at the HeartMath Institute have extended this body of scientific research by looking at how larger-scale patterns of heart activity affect the brain's functioning.
HeartMath research has demonstrated that different patterns of heart activity (which accompany different emotional states) have distinct effects on cognitive and emotional function. During stress and negative emotions, when the heart rhythm pattern is erratic and disordered, the corresponding pattern of neural signals traveling from the heart to the brain inhibits higher cognitive functions. This limits our ability to think clearly, remember, learn, reason, and make effective decisions. (This helps explain why we may often act impulsively and unwisely when we're under stress.) The heart's input to the brain during stressful or negative emotions also has a profound effect on the brain's emotional processes, actually serving to reinforce the emotional experience of stress.
In contrast, the more ordered and stable pattern of the heart's input to the brain during positive emotional states has the opposite effect. It facilitates cognitive function and reinforces positive feelings and emotional stability. This means that learning to generate increased heart rhythm coherence, by sustaining positive emotions, not only benefits the entire body, but also profoundly affects how we perceive, think, feel, and perform.
Your Heart's Changing Rhythm
The heart at rest was once thought to operate much like a metronome, faithfully beating out a regular, steady rhythm. Scientists and physicians now know, however, that this is far from the case. Rather than being monotonously regular, the rhythm of a healthy heart-even under resting conditions – is actually surprisingly irregular, with the time interval between consecutive heartbeats constantly changing. This naturally occurring beat-to-beat variation in heart rate is called heart rate variability (HRV).
Heart rate variability is a measure of the beat-to-beat changes in heart rate. This diagram shows three heartbeats recorded on an electrocardiogram (ECG). Note that variation in the time interval between consecutive heartbeats, giving a different heart rate (in beats per minute) for each interbeat interval.
The normal variability in heart rate is due to the synergistic action of the two branches of the autonomic nervous system (ANS)-the part of the nervous system that regulates most of the body's internal functions. The sympathetic nerves act to accelerate heart rate, while the parasympathetic (vagus) nerves slow it down. The sympathetic and parasympathetic branches of the ANS are continually interacting to maintain cardiovascular activity in its optimal range and to permit appropriate reactions to changing external and internal conditions. The analysis of HRV therefore serves as a dynamic window into the function and balance of the autonomic nervous system.
The moment-to-moment variations in heart rate are generally overlooked when average heart rate is measured (for example, when your doctor takes your pulse over a certain period of time and calculates that your heart is beating at, say, 70 beats per minute). However, the emWave and Inner Balance technologies allows you to observe your heart's changing rhythms in real time. Using your pulse data, it provides a picture of your HRV-plotting the natural increases and decreases in your heart rate occurring on a continual basis.
Why is HRV Important?
Scientists and physicians consider HRV to be an important indicator of health and fitness. As a marker of physiological resilience and behavioral flexibility, it reflects our ability to adapt effectively to stress and environmental demands. A simple analogy helps to illustrate this point: just as the shifting stance of a tennis player about to receive a serve may facilitate swift adaptation, in healthy individuals the heart remains similarly responsive and resilient, primed and ready to react when needed.
HRV is also a marker of biological aging. Our heart rate variability is greatest when we are young, and as we age the range of variation in our resting heart rate becomes smaller. Although the age-related decline in HRV is a natural process, having abnormally low HRV for one's age group is associated with increased risk of future health problems and premature mortality. Low HRV is also observed in individuals with a wide range of diseases and disorders. By reducing stress-induced wear and tear on the nervous system and facilitating the body's natural regenerative processes, regular practice of HeartMath coherence-building techniques can help restore low HRV to healthy values.
Heart Rhythm Patterns and Emotions
Many factors affect the activity of the ANS, and therefore influence HRV. These include our breathing patterns, physical exercise, and even our thoughts. Research at the HeartMath Institute has shown that one of the most powerful factors that affect our heart's changing rhythm is our feelings and emotions. When our varying heart rate is plotted over time, the overall shape of the waveform produced is called the heart rhythm pattern. When you use the emWave and Inner Balance technologies, you are seeing your heart rhythm pattern in real time. HeartMath research has found that the emotions we experience directly affect our heart rhythm pattern, and this, in turn, tells us much about how our body is functioning.
In general, emotional stress, including emotions such as anger, frustration, and anxiety, gives rise to heart rhythm patterns that appear irregular and erratic: the HRV waveform looks like a series of uneven, jagged peaks (an example is shown in the figure below). Scientists call this an incoherent heart rhythm pattern. Physiologically, this pattern indicates that the signals produced by the two branches of the ANS are out of sync with each other. This can be likened to driving a car with one foot on the gas pedal (the sympathetic nervous system) and the other on the brake (the parasympathetic nervous system) at the same time. This creates a jerky ride, burns more gas, and isn't great for your car, either! Likewise, the incoherent patterns of physiological activity associated with stressful emotions can cause our body to operate inefficiently, deplete our energy, and produce extra wear and tear on our whole system. This is especially true if stress and negative emotions are prolonged or experienced often.
In contrast, positive emotions send a very different signal throughout our body. When we experience uplifting emotions such as appreciation, joy, care, and love; our heart rhythm pattern becomes highly ordered, looking like a smooth, harmonious wave (an example is shown in the figure below). This is called a coherent heart rhythm pattern. When we are generating a coherent heart rhythm, the activity in the two branches of the ANS is synchronized and the body's systems operate with increased efficiency and harmony. It's no wonder that positive emotions feel so good. They actually help our body's systems synchronize and work better.
Heart rhythm patterns during different emotional states. These graphs show examples of real-time heart rate variability patterns (heart rhythms) recorded from individuals experiencing different emotions. The incoherent heart rhythm pattern shown in the top graph, characterized by its irregular, jagged waveform, is typical of stress and negative emotions such as anger, frustration, and anxiety. The bottom graph shows an example of the coherent heart rhythm pattern that is typically observed when an individual is experiencing a sustained positive emotion, such as appreciation, compassion, or love. The coherent pattern is characterized by its regular, sine-wave-like waveform. It is interesting to note that the overall amount of heart rate variability is actually the same in the two recordings shown above; however, the patterns of the HRV waveforms are clearly different.
Coherence: A State of Optimal Function
The HeartMath Institute's research has shown that generating sustained positive emotions facilitates a body-wide shift to a specific, scientifically measurable state. This state is termed psychophysiological coherence, because it is characterized by increased order and harmony in both our psychological (mental and emotional) and physiological (bodily) processes. Psychophysiological coherence is state of optimal function. Research shows that when we activate this state, our physiological systems function more efficiently, we experience greater emotional stability, and we also have increased mental clarity and improved cognitive function. Simply stated, our body and brain work better, we feel better, and we perform better.
Physiologically, the coherence state is marked by the development of a smooth, sine-wave-like pattern in the heart rate variability trace. This characteristic pattern, called heart rhythm coherence, is the primary indicator of the psychophysiological coherence state, and is what the emWave and Inner Balance technologies measure and quantify. A number of important physiological changes occur during coherence. The two branches of the ANS synchronize with one another, and there is an overall shift in autonomic balance toward increased parasympathetic activity. There is also increased physiological entrainment-a number of different bodily systems synchronize to the rhythm generated by the heart (see figure below). Finally, there is increased synchronization between the activity of the heart and brain.
Physiological entrainment during coherence.
The top graphs show an individual's heart rate variability, blood pressure rhythm (pulse transit time), and respiration rhythm over a 10-minute period. At the 300-second mark (center dashed line), the individual used HeartMath's Quick Coherence® technique to activate a feeling of appreciation and shift into the coherence state. At this point, the rhythms of all three systems came into entrainment: notice that the rhythmic patterns are harmonious and synchronized with one another instead of scattered and out-of-sync. The left side of the graphs shows the spectral analysis of the three physiological rhythms before the shift to coherence. Notice how each pattern looks quite different from the others. The graphs on the right show that in the coherence state the rhythms of all three systems have entrained to oscillate at the same frequency.
Coherence Is Not Relaxation
An important point is that the state of coherence is both psychologically and physiologically distinct from the state achieved through most techniques for relaxation. At the physiological level, relaxation is characterized by an overall reduction in autonomic outflow (resulting in lower HRV) and a shift in ANS balance towards increased parasympathetic activity. Coherence is also associated with a relative increase in parasympathetic activity, thus encompassing a key element of the relaxation response, but is physiologically distinct from relaxation in that the system oscillates at its natural resonant frequency and there is increased harmony and synchronization in nervous system and heart–brain dynamics. This important difference between the two states is reflected most clearly in their respective HRV power spectra (see figure and explanation below). Furthermore, unlike relaxation, the coherence state does not necessarily involve a lowering of heart rate, or a change in the amount of HRV, but rather is primarily marked by a change in the heart rhythm pattern.
Heart rhythm patterns during relaxation and coherence
The two graphs on the left show typical heart rate variability (heart rhythm) patterns during states of relaxation and coherence. To the right are shown the HRV power spectral density plots of the heart rhythm patterns at left. Relaxation produces a high-frequency, low-amplitude heart rhythm, indicating reduced autonomic outflow. Increased power in the high frequency band of the HRV power spectrum is observed, reflecting increased parasympathetic activity (the "relaxation response"). In contrast, the coherence state, activated by sustained positive emotions, is associated with a highly ordered, smooth, sine-wave-like heart rhythm pattern.
Unlike relaxation, coherence does not necessarily involve a reduction in HRV, and may at times even produce an increase in HRV relative to a baseline state. As can be seen in the corresponding power spectrum, coherence is marked by an unusually large, narrow peak in the low frequency band, centered around 0.1 hertz (note the significant power scale difference between the spectra for coherence and relaxation). This large, characteristic spectral peak is indicative of the system-wide resonance and synchronization that occurs during the coherence state.
Not only are there fundamental physiological differences between relaxation and coherence, but the psychological characteristics of these states are also quite different. Relaxation is a low-energy state in which the individual rests both the body and mind, typically disengaging from cognitive and emotional processes. In contrast, coherence generally involves the active engagement of positive emotions. Psychologically, coherence is experienced as a calm, balanced, yet energized and responsive state that is conducive to everyday functioning and interaction, including the performance of tasks requiring mental acuity, focus, problem-solving, and decision-making, as well as physical activity and coordination.

Steps for Quick Coherence Technique:
Step 1: Focus your attention in the area of the heart. Imagine your breath is flowing in and out of your heart or chest area, breathing a little slower and deeper than usual.
Suggestion: Inhale 5 seconds, exhale 5 seconds (or whatever rhythm is comfortable)
Step 2: Make a sincere attempt to experience a regenerative feeling such as appreciation or care for someone or something in your life.
Suggestion: Try to re-experience the feeling you have for someone you love, a pet, a special place, an accomplishment, etc. or focus on a feeling of calm or ease.
The Role of Breathing
Another important distinction involves understanding the role of breathing in the generation of coherence and its relationship to the techniques of the HeartMath System. Because breathing patterns modulate the heart's rhythm, it is possible to generate a coherent heart rhythm simply by breathing slowly and regularly at a 10-second rhythm (5 seconds on the in-breath and 5 seconds on the out-breath). Breathing rhythmically in this fashion can thus be a useful intervention to initiate a shift out of stressful emotional state and into increased coherence. However, this type of cognitively-directed paced breathing can require considerable mental effort and is difficult for some people to maintain.
While HeartMath techniques incorporate a breathing element, paced breathing is not their primary focus and they should therefore not be thought of simply as breathing exercises. The main difference between the HeartMath tools and most commonly practiced breathing techniques is the HeartMath tools' focus on the intentional generation of a heartfelt positive emotional state. This emotional shift is a key element of the techniques' effectiveness. Positive emotions appear to excite the system at its natural resonant frequency and thus enable coherence to emerge and to be maintained naturally, without conscious mental focus on one's breathing rhythm.
This is because input generated by the heart's rhythmic activity is actually one of the main factors that affect our breathing rate and patterns. When the heart's rhythm shifts into coherence as a result of a positive emotional shift, our breathing rhythm automatically synchronizes with the heart, thereby reinforcing and stabilizing the shift to system-wide coherence.
Additionally, the positive emotional focus of the HeartMath techniques confers a much wider array of benefits than those typically achieved through breathing alone. These include deeper perceptual and emotional changes, increased access to intuition and creativity, cognitive and performance improvements, and favorable changes in hormonal balance.
To derive the full benefits of the HeartMath tools, it is therefore important to learn how to self-activate and eventually sustain a positive emotion. However, for users who initially have trouble achieving or maintaining coherence, practicing heart-focused breathing at a 10-second rhythm, as described above, can be useful training aid. Once individuals grow accustomed to generating coherence through rhythmic breathing and become familiar with how this state feels, they can then begin to practice breathing a positive feeling or attitude through the heart area in order to enhance their experience of the HeartMath tools and their benefits. Eventually, with continuity of practice, most people become able to shift into coherence by directly activating a positive emotion.
