摘要
将小波变换方法应用于心电信号的自动分析 ,分别用一次微分小波和二次微分小波构造了两个具体的算法 ,对实际心电信号的分析表明 ,算法的 QRS波的检出率达到 99.6%以上 ,可以满足实际应用的要求 .
This paper describes the basic principles of wavelet transform and its application to the automatic detection of ECG signal. Two algorithms are given which are constructed by the first differential wavelet function and second differential wavelet function. Analysis results show that the detection rate has reached to 99.6%, which is satisfied in practical application.
