基于小波变换的心脑血管疾病脉搏信号分析方法

运用小波变换分析方法对心脑血管疾病患者和健康人的脉搏信号进行了特征分析,得到患者和健康人脉搏信号的不同频带能量分布比例特征。该特征在患者和健康人的脉象上有着明显的差别,可作为心脑血管疾病临床诊断时的一种参考依据。

The method of wavelet transform is used to analyze the features of pulse signals in this paper.The feature of energy distribution ratio in different frequency band is analyzed and extracted,which has obvious differences between the patients who have suffered the cerebrovascular disease and healthy people＇s pulse signals.So this method can be regarded as reference when cardiovascular disease is diagnosed.
