The Origins of Heart Rhythm MeditationModern Updates At IAM, Heart Rhythm Meditation (HRM) has been updated to incorporate what we have learned from scientific measurements of the heart, lung capacity, carbon-dioxide levels, and temperature of extremities. The most important influence has come from the study of Heart Rate Variability during HRM. These scientific studies have confimed and strengthened several key aspects of the method of HRM, especially the necessity for a full breath, coordinated with the heartbeat. We have tuned the method of HRM to produce the maximum increase in Heart Rate Variability (HRV). Recently it has been discovered that the single best predictor of heart disease is low HRV; this is a more accurate predictor than high cholesterol or high blood pressure. Heart Rhythm Meditation is the best method discovered so far for increasing HRV. Recently we discovered that the well-known mechanism called RSA (Respiratory Sinus Arrhythmia), responsible for slowing the heartrate during exhalation, is inoperative during HRM, replaced by an unknown mechanism that has the opposite effect, as shown in the diagram above. This will be the subject of future studies. The reverse-RSA effect we see in Heart Rhythm Meditators is a much stronger linkage between breath and heartbeat than is the RSA mechanism, which has only a weak effect. This may account for why it is that HRM produces such great increases in HRV. | ||
