Abstract
Heart rate variability (HRV) is a commonly employed indirect estimate of cardiac autonomic activity during sleep with limited reliability studies. Nocturnal frequency-domain HRV was reliable across differing stable sleep cycles of stage-2 (N2), slow-wave (SWS), and rapid-eye-movement (REM) sleep. Moreover, frequency- and time-domain HRV were reliable during stable and disturbed sleep, except SWS low-frequency HRV. Our finding supports nocturnal HRV as a potential tool for cardiovascular risk stratification.
