摘　　要：提出了一种基于小波变换进行心脏室颤波特征点识别的新方法。该方法首先对信号在特定不同尺度上的小波变换结果进行“多尺度交叉搜索” ,然后再在此基础上进行自适应判决检测。实践证明该方法的识别率达到 94 5% 。A novel method for the identification of ventricular wave based on wavelet transform is presentedFirst,“Multi-Scale Intersectional Search'is adopted for analysis of wavelet transform coefficients on some different scales,then adaptive detection is used on this basisThe results of practice show that it has a discrimination of 945%,and is obviously superior to any routime method
