心拍変動からみた断眠負荷の Sleep Cycle への影響

抄録

To investigate detailed characteristics of human sleep cycle, all night polysomnograms were recorded in healthy and sleep deprived subjects. R-R interval series extracted from the ECG data were analysed using FFT. Estimated low and high frequency components of R-R power spectra were evaluated. Specific change of autonomic function during sleep was observed in sleep deprived subjects.
