CHARACTERISTICS ANALYSIS FOR BODY SURFACE POTENTIAL MAPPINGOF MYOCARDIAL INFARCTION BASED ON THE WAVELETTRANSFORM PROCESSING METHOD
基于小波变换的心肌梗塞体表电位特征分析

The Wavelet Transform(WT) method has been already used to detect and filter the ECG signals. This paper introduces a new processing method for Body Surface Potentied Mapping(BSPM) using WT. We used our Virtual Heart Model(VHM) to produce the BSPM of myocardial infarction and chose a suitable WT to process it. The result shows that the BSPM processed by WT can indicate the characteristics of distribution of myocardium in different position more precisely. The topolopy revealed by it provides a new approach to applying the method using BSPM and VHM to clinical diagnose of myocardial infarction.
