摘要
作者对心电特征点的定位进行实验研究。采用局域变换算法对ＱＲＳ波及Ｔ波特征点进行准确提取，提出根据正负峰点位置对ＱＲＳ波群模式分类和利用峰值差判别Ｔ波极性的方法。局域变换算法使心电特征点的特性更为突出，唯一性较好；ＱＲＳ波群形态的峰值位置判别和Ｔ波极性的峰值判别方法计算简单，为局域变换算法的实现打下基础。
Experiment study of a method for locating ECG key points is introduced in this paper.Key points of QRS complexes and T waves are located accurately by using local transform algorithm. Based on locations of positive and negative peaks ,a method of classifying QRS complexes and using difference of peak values idendifying polarities of T waves,is presented. The local transform algorithm stresses features of key points and good uniformity is found. The calculation of the methods of discrimination of locations of peaks of QRS complexes and discrimination of polarities of peaks of T waves is simple. It lays the foundation to implement local transform algorithm.
