Heart rate variability (HRV) non-invasively assesses the activity of the autonomic nervous
system. During the past 30years, an increasing number of studies have related the …

The autonomic nervous system plays a major role in affecting the cardiac milieu and
promoting malignant ventricular activity. The measurement of heart rate variability (HRV) is a …

The last two decades have witnessed the recognition of a significant relationship between
the autonomic nervous system and cardiovascular mortality, including sudden cardiac …

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) has recently become a popular noninvasive research tool in
cardiology. Clinical assessment of HRV is frequently based on standard long‐term …

The last two decades have witnessed the recognition of a significant relationship between
the autonomic nervous system and cardiovascular mortality, including sudden cardiac …

Heart rate variability (HRV) has become a popular method for the studies of physiologic
mechanisms responsible for the control of heart rate fluctuations, in which the autonomic …

Heart rate variability (HRV) is the temporal beat‐to‐beat variation in successive RR intervals
on an electrocardiographic (ECG) recording and it reflects the regulation of the heart rate …

Heart rate variability (HRV) provides indirect insight into autonomic nervous system tone,
and has a well-established role as a marker of cardiovascular risk. Recent decades brought …
