Heart Rate Variability. The time series of successive heart periods present important
variations around its mean value, determining the phenomenon of heart rate variability …

Indices of heart rate variability (HRV) provide a window onto autonomic modulation of the
heart. HRV indices, determined in either the time or frequency domain, are closely related …

Heart rate variability (HRV) reflects the modulation of cardiac function by autonomic and
other physiological systems, and its measurement from ambulatory electrocardiograph …

Heart rate variability (HRV), the beat-to-beat variation in either heart rate or the duration of
the RR interval, has become a popular clinical and investigational tool (Task Force of the …

The article discusses method for interpreting heart rate variability (HRV). HRV reflects
change in neurohormonal activation which is an important pathophysiologic factor in …
