Abstract
A PPG PRV device for generating a PRV parameter of a PPG signal () as an estimation of a HRV parameter of an ECG signal. The PPG PRV device employs a PPG probe () and a PPG PRV controller (). In operation, the PPG probe () generate a PPG signal (). In response thereto, the PPG PRV controller () generates a normalized PPG signal (') including a plurality of pulses of the PPG signal () designated as normal pulses by the PPG PRV controller () and excluding at least one pulse of the PPG signal () designated at least one abnormal pulse by the PPG PRV controller (), wherein the normalized PPG signal (′) is HRV comparable to the ECG signal. The PPG PRV controller () derives the PRV parameter from a HRV measurement of the normalized PPG signal (′).
