Abstract :
The potential application of multiscale entropy (MSE) to analyze the heart rate variability (HRV) during different sleep stages, i.e. wake/Rapid Eye Movement (REM) /light sleep/deep sleep, was investigated. The RR sequences of 5 min from four sleep stages were analyzed by the measurements of MSE under three scales (MSE1, MSE2 and MSE3). The results demonstrated that the complexity of heart rate (HR) in non-REM(NREM) is significantly higher (p<;0.01) than that in wake and REM, and the complexity becomes higher with sleep deepening (p<;0.01). MSE3 corresponding to r=0.25*STD reveal the most powerful entropy measurement for classifying different sleep stages.
