HRV, the measurement of the time intervals between adjacent pairs of heartbeats, or simply the beat-to-beat changes in heart rate, reflects autonomic nervous system (ANS) dynamics. The students were instructed to wear heart rate variability (HRV) recorders 24 hours a day each day of the 14-day study, except for a short period after waking in the morning. Participating in the study, whose researchers included HeartMath Institute’s Director of Research Rollin McCraty and scientist Mike Atkinson, were 20 medical students at Lithuanian University of Health Sciences. It has been shown to increase the synchronization of heart rhythms between participants in a group setting as well.
The Heart Lock-In, introduced in 1992, helps to increase coherence in an individual’s heart rhythms. Now a study* has validated the tool’s effect on synchronization between the heart and geomagnetic activity, which is significant because this synchronization is associated with better health. The Heart Lock-In ® Technique, one of HeartMath’s earliest tools, has helped individuals and groups increase heart-rhythm coherence for many years.
