- Methods:This paper studied multi-scale wavelet transform of HRV signal and analyzed the statistical properties of a new measure:the standard deviation of DWT coefficients. 方法:对HRV信号进行多尺度小波变换,用DWT算法进行均方差估计;
- A new kind of time series, which is used as the ‘HRV Signals’ for the purpose of nonlinear dynamics analysis of HRV, is introduced based on the Integral Pulse Frequency Modulation (IPFM) model. 该时间序列对 于影响HRV的内在系统是一个更为直接的观察量，不但可以应用于非线性动 力学研究，还可以用于其它的一些分析方法。通过RR间期序列的功率谱与HRV 时间序列功率谱的对比，表明后者的功率谱具有较少的波峰数目和相对弱的宽 带特性，说明某些病例中RR间期的功率谱中的宽带特性是由于非线性观察函 数引起的，而不一定是系统内在混饨特性的反映。
