| 摘 要： | 在ECG信号中,QRS波群含有大量的信息,它对ECG信号的分析具有指导意义,因而QRS波群的检测得到了广泛地研究。文章通过对小波处理过程的研究,发现采用快速卷积的小波变换,通过判断小波相位符号的变化,可以准确地定位R波;这种手段本质上依然是过零点的检测,但是由于不依赖于幅度域值,所以更加有效。

| Abstract: | In ECG signal analysis,the information contained in QRS complexes of the electrocardiogram(ECG) signal counts much.That is the reason why the detection method of QRS complexes is widely researched nowadays.By deducing the wavelet transform,it is found that by fast convolution,the phase information can be obtained,by which the R-wave apex can be confirmed accurately.It is another access to detecting zero-amp of wavelet transform in fact,but it is more efficient because it has little reliance on the amp-threshold. |
