Agreement between Fitbit Versa 4 and a reference standard on time-domain nocturnal heart rate variability: A pilot study
Strong correlation and acceptable agreement between Fitbit Versa 4 HRV measurements and reference standard HRV measurements derived from ECG provide preliminary support for using Fitbit Versa 4 to measure nocturnal HRV outside laboratory settings.
