“…At present, only systolic annotations are available for evaluation. A total of five performance matrices are calculated to evaluate the systolic peak detection using Equations ( 6)- (10), which includes sensitivity (SN), positive predictivity (PPV), accuracy (ACC), error rate (ERR), and mean absolute error (MAE). Complete results for systolic peak detection of the two CSL data and 43 IHD subjects' data are shown in Table 3.…”

“…• PPG: onset, systolic, notch, and diastolic peaks • VPG: u, v, and w peaks • APG: a, b, c, d, and e peaks Photoplethysmogram is recorded using a pulse oximetry device, which is sensitive to skin structure (color), skin temperature, electrical noise, motion artifacts, and measuring environment (9). PPG is also significantly affected by the physiological variability of aging, hypertension, diabetes, vessel compliance, and apnoeic episodes (10). These have caused the peak detection of PPG to become challenging.…”

“…Derivatives of PPG: according to literature, the first and second derivatives of PPG also provide valuable information or features while predicting BP. They are called various names such as PPG', PPG" or Velocity of PPG (VPG), Acceleration of PPG (APG), or FDPPG (First Derivative of PPG), SDPPG (Second Derivative of PPG) [52][53][54] (Figure 2). To find the VPG and APG from PPG, MATLAB's 'diff' function was used.…”

“…Furthermore, baseline modulation was removed from the PPG data. This baseline wander can be a result of losing body and sensor contact due to the subject's unwanted movement during measurement or because of abnormal breathing [36].…”
