Abstract

Detection of T wave alternans is constructed as a statistical problem in the present work. The objective was to evaluate the performance of a group of statistical tests in detecting a set of artificially generated alternans episodes and in the European ST (EST) database. Three statistical tests, standard t-test, matched pair t-test, and Rayleigh test, were performed on numerically generated sequences and also on simulated alternans episodes in a rolling sequence of 32 beats. Application of statistical tests to the numerical simulations and beat simulations resulted in 100% detection accuracy. Statistical tests also detected multiple episodes of both visible and invisible alternans in the EST database. Statistical tests seem to provide a complementary and a computationally efficient solution to alternans detection problem in surface ECG.
统计背景下T波交替的存在——一种测量低振幅交替的新方法
在本工作中,T波交替的检测被构造为一个统计问题。目的是评估一组统计测试在检测一组人为产生的交替事件和欧洲ST (EST)数据库中的表现。三种统计检验,标准t检验,配对配对t检验和瑞利检验,对数字生成的序列和模拟交替发作的32拍滚动序列进行了检验。将统计测试应用于数值模拟和温度模拟,检测精度达到100%。统计测试还在EST数据库中发现了可见和不可见交替的多个片段。统计检验似乎为体表心电图的交替检测问题提供了一种补充和计算效率高的解决方案。
