多导同步心电图的QRS波检测及起止点的确定

Identification of QRS Complexes and Their Boundaries in Multi-Lead Synchronized ECG

本文采用从单导到多导的检测方法 ,首先利用小波变换实现单导 QRS波的检测 ,在此基础上 ,利用位置相关法进行多导 QRS波的检测 ,并利用心电信号的 2 1尺度小波变换的平方值来确定 QRS波的起止点。

In this paper we present an algorithm for detection of QRS complexes from singlelead to multi\|lead in ECG.We first detect QRS complexes in single\|lead ECG using wavelet\|transformation of signals on the bano of ahich we then detect QRS complexes in multi\|lead ECG according to their position correlation; and we determine onsets and ends of QRS complexes with the square value of 2\+1 scale wavelet\|transformation of the ECG signals.Tests of large quantities of data have proven the algorithm satisfactory.\;
