WebIt is important to extract significant points such as systolic peaks, onsets, and dicrotic notches from PPG waveforms accurately for PRV analysis. 12 The onset of the PPG waveform is due to the commencement of blood expulsion from the heart to the aorta, while the dicrotic notch is the end of blood ejection or the closure of the aortic valve. WebFeb 20, 2007 · The PPG waveform comprises a pulsatile ('AC') physiological waveform attributed to cardiac synchronous changes in the blood volume with each heart beat, and is superimposed on a slowly varying ('DC') baseline with various lower frequency components attributed to respiration, sympathetic nervous system activity and thermoregulation.
