What is the relationship between heart-rate variability and coherence?
Heart-rate variability (HRV) is the normal, naturally occurring variations or changes in the amount of time between heartbeats. This is different than your overall heart rate – the number of beats that occur in any given minute. It is directly related to coherence, the measure of which derived from HRV, or the heart’s rhythm over time. Coherence reflects the orderly and harmonious connectedness between various systems in the body such as the heart, brain and respiratory and immune systems. When our heart-rate variability is functioning normally, not too great or too little, we are able to achieve this coherence, which can be measured by our heart-rhythm patterns with a monitoring device such as an electrocardiogram or emWave device.
