摘要
首先研究了ECG中各波特征点的识别,在Q波起点和T波起始点识别的基础上介绍了计算机自动测量QT间期和T波面积的算法;解决了QT间期手工测量时不同测量者测量差异很大以及T波面积无法人工测量的问题;结果表明计算机应用此算法能准确的测量QT间期和T波面积,为临床诊断心肌缺血提供了新的方法,特异度以及敏感度均达到要求.
This paper first studies the detection of fiducial point in ECG on the basis of the detection of starting point in Q wave and terminal point in T wave,and then introduces an algorithm of automatic measuring QT interval and T wave area. At the same it has solved the problem that different person achieves different results by hand and T wave area can＇t be measured by hand. The results indicate that using this algorithm computer can calculate QT interval and T wave area precisely. It also provides a new method for diagnosing myocardial ischemia; the specificity and the sensitivity of the method come up to the standard required.
