FP may suffice for resting HRV in healthy subjects; leaves open its reliability versus ECG during cognitive stress.
Does finger plethysmograph accurately measure heart rate variability compared to ECG in healthy subjects?
Finger plethysmography may be adequate for resting HRV measurement but is less reliable than ECG during cognitive stress tasks.
