Does a photoplethysmography finger sensor provide reliable and valid heart rate variability metrics compared to ECG and heart rate monitors?
A PPG finger sensor demonstrates adequate test-retest reliability and concurrent validity for measuring heart rate variability in supine and seated positions compared to standard ECG and HRM devices.
Effect estimate: ICC 0.60-0.93
p-value: p=<0.05
The purpose of the current study was to determine the test–retest reliability and concurrent validity of a photoplethysmography (PPG) finger sensor when collecting heart rate variability (HRV) metrics in reference to electrocardiography (ECG) and heart rate monitor (HRM) devices. Five minutes of R-R interval data were collected from 45 participants (23 females; age: 23.13 ± 4.45 yrs; body mass index: 25.39 ± 4.13 kg/m2) in the supine and seated positions in testing sessions 48 h apart. Moderate-to-excellent test–retest reliability of the HRV data collected from the PPG sensor was identified (ICC2,1 = 0.60–0.93). Additionally, similar standard errors of the mean, coefficient of variation, and minimal detectable change metrics were observed across all devices. Statistically significant (p < 0.05) differences were identified in the HRV data between the PPG sensor and ECG and HRM devices; however, these differences were interpreted as trivial-to-small (g = 0.00–0.59). Further, the PPG sensor tended to only overestimate HRV metrics by <0.5 ms and near perfect relationships (r = 0.91–1.00) and very large-to-near perfect agreement (CCC = 0.81–1.00) were identified between collection methods. The PPG sensor demonstrated adequate test–retest reliability and concurrent validity in both the supine and seated resting positions.
Rogers et al. (Wed,) reported a observational. Photoplethysmography (PPG) finger sensor vs. Electrocardiography (ECG) and heart rate monitor (HRM) devices was evaluated on Test-retest reliability and concurrent validity of heart rate variability metrics (ICC 0.60-0.93, p=<0.05). A photoplethysmography finger sensor demonstrated moderate-to-excellent test-retest reliability (ICC 0.60-0.93) and near-perfect agreement (CCC 0.81-1.00) with ECG and HRM devices for HRV metrics.
