小波变换在心搏异常突变点检测中的应用

Application of wavelet transform on the determination of catastrophe points for abnormal heart beating

多普勒信号反映了血流速度,多普勒信号突变点的数量,一定程度上可以对冠心病预报,并反映心肌血 管路径状况.本文应用小波变换对多普勒频谱进行分析.通过临床实验.结果显示出突变点的数量对缺血性心 肌病具有较高的诊断价值。

Doppler signal reflects blood flow velocity, and the number of the catastrophe chop points can be used to predict coronary heart diseases and route status of blood vessel. Through wavelet transform, the Doppler spectrum can be analyzed and number of catastrophe points can be determined. It is shown that the number of catastrophe points is useful for diagnosis of cardiac diseases.
