Pulse Rate Variability Analysis Using Remote Photoplethysmography Signals
Sensors, 2021 Pulse rate variability (PRV) refers to the change in the interval between pulses in the blood volume pulse (BVP) signal acquired using photoplethysmography (PPG). PRV is an indicator of the health status of an individual’s autonomic nervous system.
