摘　　要：针对便携式12导数字化心电导联线不易识别心电信号QRS波的问题,基于信号处理,利用小波函数良好的时频局域化特性和对时变信号分析的优越性,运用小波变换的奇异点与信号变化剧烈处间的联系理论,以软件方法实现了QRS波的检测.仿真结果表明,该方法对于QRS波、特别是R波的检测,有较高的精确度.In order to solve the problem that it is difficult to detect the QRS wave of ECG based on portable digital 12-lead ECG cable,according to the characteristics of time-domain and frequency-domain based on the signal processing method,and the theory of the relation between the singularity and the severe changing point of signal,the detection of QRS wave of ECG was achieved.The simulation results showed that the method had more accuracy for diagnosing QRS wave,especially R wave.
