摘    要:目的 检测与分析心绞痛患者的T波交替(T wave alternans,TWA).方法 先采用谱分析法检测European ST-T数据库中部分不同程度心绞痛患者是否存在TWA现象,再采用相关分析法检测出心动周期中具体发生TWA的时间段的数目和长度等.结果 文中所有被检测的心绞痛患者均有TWA发生.结论 TWA的出现次数基本上与患者心绞痛的严重程度有关,随着心绞痛程度的加强,TWA出现的次数增多;但不能判断TWA幅度和持续拍数是否与心绞痛严重程度有关.

关 键 词:T波交替  谱分析法  相关分析法  心绞痛

Abstract:Objective To detect and analyse the TWA(T wave alternans,TWA) in angina patients.Methods The spectral analysis method was used to detect the TWA status of patients with different degrees of angina in european ST-T database.Then correlation analysis method was used to obtain the times and length of TWA,and etc.Results TWA appeared in all of angina patients who were detected in this paper.Conclusion The results showed that TWA appeared more frequently in the data of serious angina than general angina.The times of TWA happenning is relative to the angina degree.The higher the angina severity is,the more the TWA times are.But there is no correlation between TWA amplitude or the number of its consecutive beats and severity of angina.
Keywords:T wave alternans   spectral analysis method   correlation analysis method   angina
