Key result
A PPG finger sensor shows near-perfect agreement with ECG and HRM devices for HRV metrics.
Why the study?
The study was conducted to determine the test-retest reliability and concurrent validity of a photoplethysmography finger sensor for collecting heart rate variability metrics compared to electrocardiography and heart rate monitor devices.
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.
Rogers et al. (2025) reported an 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.
