N2 - This study compares the accuracy of heart rate variability (HRV) parameters estimated from digital (finger) and radial (wrist) arteries using a micro-electromechanical systems (MEMS) strain plethysmography (SPG) sensor. For this purpose, the data from 15 subjects were collected and annotated. Simultaneously with SPG, the electrical activities of the heart recorded using a single-lead electrocardiogram (ECG) sensor on subjects. Beat-To-beat intervals of ECG and SPG recordings were calculated based on the distance between consecutive systolic peaks in both signals. It was demonstrated that HRV parameters such as meanNN, SDNN, RMSSD, PNN50, and LF/HF can be estimated from SPG recordings. The mean differences between the SPG recordings from the digital artery and the corresponding reference values from ECG were found to be 0.0 ms, 0.00 BPM, 1 ms, 1.6 ms, 0.5747%, and 0.0332, respectively. On the other hand, the mean differences were 0.1 ms, 0.00 BPM, 1 ms, 3.5 ms, 5.11%, and-0.0151, respectively for the SPG recordings from the radial artery. These findings suggest that the fingertip is a more reliable arterial site for estimating HRV parameters.
