Abstract


Sympathetic nerve activity (SNA), blood pressure and heart rate (HR) are lower in a Non-REM sleep than in wakefulness. Spectrum analysis of heart rate variability (HRV) is a non-invasive procedure that provides quantitative information on sympathetic and parasympathetic (PNS) systems control. The aim of this work - to investigate the high frequency (HF) of heart rate dynamics during the REM sleep stage. The results of investigation indicated that HF trends are diverse: some increased and the others decreased.
