| 摘 要： | 本文把小波变换应用于心电信号的识别。探讨了伸缩尺度和伪频率(译自pseudo-frequency)之间的关系；利用二进双正交样条小波对室扑信号按Mallat算法进行小波分解；提出了心室扑动和心室颤动信号的小波变换识别方法。

| Abstract: | Wavelet transform in used to identify the ECG signal.The relation between scale and pseudo-frequency is discussed.The ventricular flutter ECG signal is decomposed with a dyadic biorthogonal spline wavelet by Mallat algorithm.A method based on wavelet transform is proposed to identify ventricular flutter and ventricular fibrillation signal. |
