Based on the modulus maxima at each scale of wavelet transform, this paper does a research into the detection of S-T segment of abnormal ECG, especially that of myocardial infarction.

基于小波变换的各个尺度上模极大值，本文深入研究了异常心电信号尤其是梗死发生时S - T段的检测。

In this paper, several characteristics of ECG from patients, such as QRS complex and its onset and offset T wave and S-T segment, has been detected using wavelet method.

本课题基于小波理论设计软件算法，提出了模极值线群方法，抽取心电信号中若干具有临床价值的特征：QRS波群组态及其起点和终点、T波、S-T段。
