| 摘 要： | 以PhysioNet Library的QT database标准心电图信号为研究对象,以matlab软件作为研究平台,首先对心电图信号进行了2次滤波,然后对QRS波群进行检测,再次对T波及T波结束点进行了定义,最后对测试结果进行了分析,较准确地得到了QRST波的相关信息,效果良好。

| Abstract: | QT database standard ECG（electrocardiogram） signal of PhysioNet Library was taken as the research object,and Matlab software as the research platform.Firstly,ECG signal was filtered two times;secondly,QRS wave group was detected;thirdly,T wave was detected and the T-end point was defined;and finally,the result was analyzed.The information of QRST wave was thus accurately obtained,so the algorithm works. |
