英文摘要 | Heart rate variability (HRV) is a useful clinical tool for autonomic function assessment and cardiovascular diseases diagnosis. It is traditionally calculated from a dedicated medical electrocardiograph (ECG). In this paper, we demonstrate that HRV can also be extracted from photoplethysmograms (PPG) obtained by the camera of a smartphone. Sixteen HRV parameters, including timedomain, frequency-domain, and nonlinear parameters, were calculated fromPPG captured by a smartphone for 30 healthy subjects and were compared with those derived from ECG.The statistical results showed that 14 parameters (AVNN, SDNN, CV, RMSSD, SDSD, TP, VLF, LF, HF, LF/HF, nLF, nHF, SD1, and SD2) from PPG were highly correlated (r>0.7, p<0.001) with those from ECG, and 7 parameters (AVNN, TP, VLF, LF, HF, nLF, and nHF) from PPG were in good agreement with those from ECG within the acceptable limits. In addition, five different algorithms to detect the characteristic points of PPG wave were also investigated: peak point (PP), valley point (VP), maximumfirst derivative (M1D), maximumsecond derivative (M2D), and tangent intersection (TI). The results showed that M2D and TI algorithms had the best performance.These results suggest that the smartphone might be used for HRV measurement. |
