Abstract

A novel method for the identification of ventricular wave based on wavelet transform is presented. First, "Multi-Scale Intersectional Search" is adopted for analysis of wavelet transform coefficients on some different scales, then adaptive detection is used on this basis. The results of practice show that it has a discrimination of 94.5%, and is obviously superior to any routime method.

摘要

提出了一种基于小波变换的心室波识别新方法。首先，采用“多尺度交叉搜索”对不同尺度上的小波变换系数进行分析，然后在此基础上进行自适应检测。实践结果表明，其识别率为94.5%，明显优于任何常规方法。
