摘要: 提出一种实时心电监控中的ST段检测方法,利用拟合法提取等电位线,采用小波变换监测QRS波群,结合J+X法及T波起点检测方法达到准确检测ST段电位的目的,在实时监控中设计实现一种ST段报警记录信息。长时间的心电数据库验证及临床检验证明该方法具有较好的准确性及实用性。

Abstract: This paper proposes a detection method of ST segment change in real-time Electrocardiography(ECG) monitoring, which uses line-fitting to extract the baseline, uses wavelet transform to monitor QRS complex, and combines J+X method and T wave detection method to attain the feature point of ST segment. A ST segment recorded message is designed in real-time monitoring. Through a long period of standard database simulation and clinical tests, this method is proved to be accuracy and useful.

Key words: Electrocardiography(ECG), ST segment, Wavelet Transform(WT)
