Key result
Ballistocardiogram-derived heart rate variability showed high correlation (r=0.97-0.98) and low relative errors (5-6%) compared to ECG during rest, Valsalva, and post-exercise.

Does a ballistocardiogram (BCG) accurately estimate heart rate variability compared to a standard electrocardiogram (ECG) during rest and autonomic stress in healthy subjects?
Effect estimate: Correlation coefficients 0.97, 0.98, and 0.98
Ballistocardiography provides an accurate, non-constrained alternative to ECG for measuring heart rate variability and assessing cardiac autonomic modulation.
Shin et al. (2011) conducted an observational in Healthy (n=15). Ballistocardiogram (BCG) vs. Electrocardiogram (ECG) was evaluated on Heart rate variability (HRV) parameters (Correlation coefficients 0.97, 0.98, and 0.98). Ballistocardiogram-derived heart rate variability showed high correlation (r=0.97-0.98) and low relative errors (5-6%) compared to ECG during rest, Valsalva, and post-exercise.
