The total percent of phase synchronization (S index) between 0.1 Hz oscillations in HRV and PPGV was lower in patients three weeks after myocardial infarction (15.7%) compared to healthy subjects (33.3%).
Observational (n=163)
Absolute Event Rate: 15.7% vs 33.3%
Introduction Complexity of cardiovascular system (CVS) and its regulatory mechanism draws high researcher’s interest to this system. However, many problems are yet to be solved. It is well known that many interacting oscillation processes of different origin are present in CVS 1. Many approaches have been utilized to study regulatory mechanisms of CVS, such as analysis of
Kiselev et al. (Thu,) conducted a observational in Healthy, Myocardial Infarction, Hypertension (n=163). Phase synchronization (S index) between 0.1 Hz oscillations in HRV and PPGV vs. Healthy subjects was evaluated on Total percent of phase synchronization (S index). The total percent of phase synchronization (S index) between 0.1 Hz oscillations in HRV and PPGV was lower in patients three weeks after myocardial infarction (15.7%) compared to healthy subjects (33.3%).
