摘　　要：本文介绍了VC平台下开发的心音信号小波分析系统。小波分析是通过在VC中调用Matlab中的小波分析工具箱形成的动态链接库。通过对部分心音信号分析可知:对心音信号的小波可有效地区别正常心音和异常心音的信息,可为临床医学诊断提供一定的理论依据。This paper introduces the heart sound signal wavelet analysis system developed under the VC platform. Wavelet analysis is done via a dynamic link library formed by calling the wavelet analysis toolbox in Matlab in VC. Through the analysis of some heart sound signals, it is shown that the small waves of heart sound signals can effectively distinguish the information of normal and abnormal heart sound, which can provide certain theoretical basis for clinical diagnosis.
