【摘要】 目前小波分析已经用于心电信号(ECG)的R波峰点检测,但是对QRS波群的具体形态和起止点位置的检测研究较少,P波和T波的分析也是心电图计算机自动分析的难点。为解决心电信号各波形成分的综合检测问题,基于小波变换技术构建一系列检测方法、检测准则和阈值参数,检测和识别QRS波群、P波、T波的具体形态和位置。实验结果表明,所提出的综合检测算法具有较好的鲁棒性,能够较好地抑止或消除基线漂移、高频干扰等外部因素,以及大T波、大S波、高U波、波形融合等自身病态因素对波形综合检测产生的影响。更多还原

【Abstract】 Synthesis detection of electrocardiographic(ECG) including QRS complex,P wave,T wave is difficult.Wavelet transform is used and a series of detection methods,detection rules and thresold paramters is developed to detect morphology and position of ECG components.Test results show that the synthesis detection algorithm is robust,the influence of extern noise is removed and restrained such as baseline,high frequency,and self annormality equation such as big T wave,big S wave,high U wave and wave fusion.更多还原
