为了评估REM和NREM睡眠期间心率及其频谱参数的特征波动，获得了整夜记录的心率变异性的频谱分解。在分析中使用了时变自回归模型，因为它允许实时和瞬时发作，评估心率变异性的频谱参数，从而分析自主神经系统的行为。这项研究使用了来自三名健康受试者的三个整夜记录。研究中得到的结果与文献中的结果是一致的：当REM值与NREM睡眠期比较时，低频功率和LF/HF比值增加，而HF功率减少。高频范围内自回归模型的极点有助于区分REM和NREM睡眠周期。当对NREM进行评估时，极点在酉圆处趋于非常接近，而在REM中，该极点远离酉圆，其相位变得不稳定
Spectral decomposition of the heart rate variability during whole night recordings was obtained, in order to assess the characteristic fluctuations in the heart rate and their spectral parameters during REM and NREM sleep stages. A time-varying autoregressive model was used in the analysis since it allows both real time and transitory episodes evaluation of spectral parameters of the heart rate variability and consequently an analysis of the autonomic nervous system behavior. Three whole nights records coming from three healthy subjects were used in the study. The results obtained during the study are in accordance with the previous ones in literature: an increment in LF power and in LF/HF ratio and a decrement in HF power when REM values are compared with NREM sleep stage. The pole of the autoregressive model in the HF range helps to separate the REM and NREM sleep epochs. When NREM is evaluated, the pole tends to be very close at unitary circle, while in REM this pole goes far from the unitary circle and its phase becomes less stable
