摘要 对心率变异性(HRV)进行了研究,比较了心率正常者与心率失常者HRV之间的最大李雅普诺夫指数上的差别。人在正常状态和病理状态下的HRV信号最大李雅普诺夫指数是不同的,当出现病理心血管事件时,指数α减少,因此李雅普诺夫指数可作为人体是否异常或处于何种异常状态的特征刻画指标,本文心率正常者HRV信号的最大李雅普诺夫指数为0.45907,心率不齐者的最大李雅普诺夫指数是0.41472。它们均为混沌信号,但是处于心率不齐状态的节律混沌程度明显比处于心率正常状态的节律混沌程度低。 Using non-linear dynamics methods, we have comparatively analyzed the HRV （heart rate variability ） of the healthy people and the HRV of those with arrhythmia. The Lyapunov exponent of the healthy group＇s HRV is different from that of the arrhythmia group＇s HRV. The largest Lyapunov exponent of the healthy people＇s HRV is 0.45907. But in the abnormal situation, the value of α reduces, and the largest Lyapunov exponent of the arrhythmia group＇s HRV is 0. 41472. They are both chaotic system, however the level of the chaos of those with arrhythmia is apparently lower than that of the healthy people.
