摘　　要：心电信号自动分析技术目前只能分析出常见的心律失常,对一些发病率低的心律失常还不能做出正确诊断,针对以上问题做了详细研究。首先论述了小波变换滤除心电信号中肌电干扰、工频干扰和基线漂移的过程;然后介绍了QRS波群和ST段的检测方法,并用数学方法定义了十三种心律失常的类型。文中的方法实时性强、检测效率高而且心律失常分析的种类多,具有一定的临床应用价值。ECG signal automatic analysis technology can only analyze the common arrhythmia at present, has not been able to make the correct diagnosis for some of the low incidence of arrhythmia, so do detailed research for the above-mentioned problem. First elaborate the process of the Wavelet Transform filtering the myo-eleetrical interference, the power frequency interference and the baseline drift, then introduce the detective method of the QRS complex and the ST segment, and define 13 type of arrhythmia with the mathematical method. In paper the method of strongly real-time, detective high-efficiency and many types of arrhythmia analysis have the certain clinical practice value.
