The results from nine subjects show that power associated with low frequency is higher in REM sleep than in NREM sleep, while powerassociated with high frequency is significantly higher inNREM sleep thanin REM sleep.
Abstract
In this work, in order to evaluate whether autonomic differences distinguish REM sleep and NREM sleep through the whole sleeping period, statistical analysis on spectral power associated with low frequency and high frequency bands were performed on the whole polysomnographic recording, considering the sleep cycle as a unit of sleep. Our results from nine subjects show that power associated with low frequency is higher in REM sleep than in NREM sleep, while power associated with high frequency is significantly higher in NREM sleep than in REM sleep. Differences between REM sleep and NREM sleep are not of the same magnitude within the whole sleep episode and, independent of sleep stages, specific trends are observable in the autonomic control of heart rate during the night.

Noninvasive studies confirmed the early morning rise of the markers of sympathetic activity and the circadian pattern of sympathovagal balance, and data indicate that the ominously increased rate of cardiovascular events in the morning hours may reflect the sudden rise of sympatheticactivity and the reduction of vagal tone.

The arousal data along with Stage 2 sleep transition data support the contention that increases in central nervous system sympathetic activity precede and possibly play a role in the initiation of REM sleep and arousals during sleep.

The sympathetic predominance that characterizes wakefulness decreases during non-REM sleep, is minimal in slow-wave sleep, and surges toward mean awake levels during REM sleep, while the autonomic balance is shifted toward parasympathetic predominance during slow- wave sleep.

Heart rate changes during sleep were analyzed, with the aid of a minicomputer, for a group of 20 healthy subjects and showed that the HR decrease during stages 1, 2, 3, and 4 is caused by augmented parasympathetic input.

Sleep stage specific, time domain and frequency domain changes in heart period variability are found, particularly using spectral analysis of heart period, and these results support other investigations demonstrating stage 2 sleep is associated with increased parasympathetic influences and REM sleep isassociated with increased sympathetic and neurohumoral influences.

The authors' findings show a progressive and significant reduction in the LF/HF ratio through sleep stages S1–S4, as a result of an increase in the HF component; this indicates the prevalence of parasympathetic activity during slow-wave sleep.

The results suggest that increases in heart rate and cardiac sympathetic activity early in the sleep period are, in part, a compensatory reaction to the concomitant thermoregulatory changes observed.
