Heart Rate Variability

Heart Rate Variability Photo

"...there are organism states in which the regulation of life processes becomes efficient, or even optimal, free-flowing and easy. This is a well established physiological fact. The fact that we, sentient and sophisticated creatures, call certain feelings positive and other feelings negative is directly related to the fluidity or strain of the life process." - Antonio Damasio

Heart Rate Variability refers to the beat-to-beat differences between each heartbeat. Research suggest that your heart has its own resonant frequency in which your heart and lungs work together most effectively. Life stressors, ill health and poor environmental conditions can lead to ineffective breathing patterns which negatively influence the heart, brain and gut. Poor heart rate variability is associated with increase mortality risk, decreased immune function and poor stress recovery.

The Coherent State

The left side of the scale shows the impact of irregular unhealthy breathing patterns on the heart rate and blood pressure rhythm.

The right side of the scale shows the changes resulting from the individual's resonant breathing.

Enhanced Performance Training® uses an EKG assessment (leads attached to the chest, arms or legs or a photoplethysmograph attached to a finger along with a respiration belt around your waist) to determine your resonant frequency.

Research suggests HRV directly influences your emotions and your immune system through your body's first line of defense against ill health by modifying the balance of glucocorticoids such as cortisol, DHEA (dehydoepiandosterone) and salivary IgA (immunoglobulin A).

HeartMath training is used by over 50,000 business leaders, professional sports coaches, health professionals and people all over the world. HeartMath tools are taught at the Stanford Business School and London Business School. Additionally, HeartMath research has been featured in respected publications such as Harvard Business Review, Wall Street Journal, Financial Times, American Journal of Cardiology and Stress Medicine.

Heart Rate Variability training utilizes the NeXus-10 and HeartMath's emWave and Alive technology which provides feedback on your heart and lung coherence as well as the impact of emotions on your heart rate in real time. For more information visit: www.heartmath.com.


Using your resonant frequency and positive emotional practices your cardiorespiratory system will be strengthened. Benefits include:
