摘要

将离散小波变换作为体表电位图的时/空联合分析工具。将联合时/空分析的结果与以往利用积分图所做的工作进行了比较。小波变换揭示了心脏信号在时间和空间方面的密切关系。作者的工作结果表明，小波变换的多分辨率信号分解为评估体表电位图提供了一种新的有用的方法

Multiresolution analysis of PTCA isopotential maps

The discrete wavelet transform is applied as a joint time/space analysis tool for body surface potential maps. The results of the joint time/space analysis are compared with previous work done by using integral maps. The wavelet transform revealed the close relation between temporal and spatial aspects of cardiac signals. The results of the authors' work suggest that the multiresolution signal decomposition via wavelet transforms provides a new and useful approach to evaluate body surface potential maps.<>
