Heart Rate Variability | Community Health

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats, measured by the variation in the beat-to-beat interval. It is an important indicator of cardiovascular health and can be measured using various methods, including ECG, blood pressure, and photoplethysmography.
