Key result
Acceleration plethysmography showed high correspondence with electrocardiography for measuring heart rate variability, with coefficients of determination ranging from 0.9676 to 0.9968 (p<0.01).

Does the Acceleration Plethysmography (APG) system accurately measure heart rate variability compared to standard ECG?
Effect estimate: Coefficient of determination 0.9676-0.9968
p-value: p=<0.01
The Acceleration Plethysmography system provides heart rate variability measurements that closely correspond to standard ECG, suggesting it could be a useful and simple tool for evaluating autonomic modulations.
Takada et al. (2008) conducted a cross-sectional in Healthy volunteers (n=6). Acceleration Plethysmography (APG) vs. Electrocardiography (ECG) was evaluated on Correspondence of the a-a interval (Taa) of APG and the R-R interval (TRR) of ECG (Coefficient of determination 0.9676-0.9968, p=<0.01). Acceleration plethysmography showed high correspondence with electrocardiography for measuring heart rate variability, with coefficients of determination ranging from 0.9676 to 0.9968 (p<0.01).
