PPGV may substitute for HRV supine at rest; leaves open validity during upright posture or exercise.
Does photoplethysmography variability (PPGV) accurately reflect heart rate variability (HRV) during sympathetic stimulations?
PPGV is a reliable surrogate for HRV in resting supine conditions but loses accuracy during physical activity and upright posture.
Charlot et al. (2009) studied this question.
