An overview of heart rate variability metrics and norms
Healthy biological systems exhibit complex patterns of variability that can be described by
mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals …

A critical review of ultra-short-term heart rate variability norms research
Heart rate variability (HRV) is the fluctuation in time between successive heartbeats and is
defined by interbeat intervals. Researchers have shown that short-term (∼ 5-min) and long …

A practical guide to resonance frequency assessment for heart rate variability biofeedback
Heart rate variability (HRV) represents fluctuations in the time intervals between successive
heartbeats, which are termed interbeat intervals. HRV is an emergent property of complex …
