Short-term heart rate variability: Easy to measure, difficult to interpret

Akselrod et  al1 were the first to report that the analysis of spontaneous fluctuations in RR interval could provide direct insight into the physiology of the autonomic control branches. Since then, heart rate variability (HRV) analysis2 has become the most used noninvasive tool to evaluate autonomic control m echanisms and to predict mortality risk in several clinical conditions. As explained in the 1996 Task Force document,2 the term HRV analysis accommodates a number of methodologies despite their major computational and physiological interpretive differences.
