摘　　要：实现心电图QRS波检测的算法有很多 ,本文介绍了一种算法 ,即利用小波变换的多尺度特性 ,可以将QRS波从高P波、高T波、噪声、基线漂移和伪迹中分离出来。并采用MicrosoftVisualC + + 5 0编程实现算法。使用该方法对MIT BIH心电数据库中带有严重基线漂移和噪声的心电信号进行处理。对QRS波的识别率高达 99 8%。文中给出程序设计要点和程序流程图。There are many ways to detect ECG QRS waves. In this paper, we introduce an algorithm based on wavelet transforms (WT's) which has been developed for detecting ECG characteristic points. With the multi-scale feature of WT's, the QRS complex can be distinguished from high P or T waves, noises, baseline drift, and artifacts. By using this method, the rate of recognition of QRS complexes is as high as 99.8% for ECG signals in MIT/BIH database, which are even with serious baseline drift and noises.
