Synthesized PPG waveform based on the unfit template. The optimal parameters of the synthesized unfit PPG waveform are shown in the row corresponding to the unfit group in Table 1. Unfit means that the heart rate cannot be determined and the systolic and diastolic waves cannot be distinguished. Here, MSE is the mean square error between the synthetic PPG and the template PPG, and r is the correlation coefficient. This figure shows that the proposed model cannot synthesize the unfit PPG pulses.
