摘要: The authors investigated the autonomic nervous activity during sleep stages by means of power spectrum density heart rate variability signal. Spectral estimation was performed autoregressive modelling RR series. data obtained suggest an augmented sympathetic REM and a progressive decrease it when passing from awake state to 1,2,3-4.
