Abstract

In accordance with the character of heart rate variability(HRV) signal, we have divided HRV signal into 1/f fractal component and 1/f non-fractal component by use of wavelet transform. This division will be beneficial to the acqusition of the character of HRV signal as well as to the quantitative analysis of 1/f fractal component.

摘要

根据心率变异性（HRV）信号的特征，我们利用小波变换将HRV信号分为1/f分形分量和1/f非分形分量。这种划分将有利于HRV信号特征的获取以及1/f分形分量的定量分析。
