A Robust Beat-to-Beat Artifact Detection Algorithm for Pulse Wave

Figure 8

Five types of pulse waveforms: (a) one peak, (b) two peaks (main peak and dicrotic peak), (c) three peaks (main peak, tidal peak, and dicrotic peak), (d) the notch is lower than the onset, and (e) an inflection point appears around the main peak.
