摘　　要：本文描述了一种基于两进小波变换(D_yWT)的QRS波检测器。小波尺度的选择是基于心电信号的频谱的特性,并根据多尺度选择方法判决检测心电QRS波。实验结果表明,对于在有强大的噪声和严重的基线漂移干扰下的心电信号能够有效的识别。We develop a new QRS comprex detector based on the dyadic wavelet transform (DyWT). We choose the scale of wavelet by the ECG's frenquent characteristic and judge based on the mutil-scale selection method. The experiment results show that this method has excellent performance to QRS complex detect under great noise and malformed baseline drift.
