心电图自动诊断系统的研制

摘要

本文利用数字信号处理和波形识别技术，对心电图的QRS波、P波、T波的时段进行了计算机的自动检测并对室性期前收缩等15种异常心电进行自动诊断。打印输出相应的诊断报告。为了检验本系统的稳定性和可信度，本文还利用美国麻省理工学院的MIT-BIH数据库对本文所使用的方法进行了检测，取得了较好的效果。%The duration of QRS wave,P wave and T wave of ECG can be computerized auto-detected with digital signal process and waveform recognition technology. It can diagnose 15 kinds of abnormal ECG such as ventricular presystole automatically and print out corresponding diagnosis reports. In order to verify the systems stability and creditability, we used American MIT-BIH database to test our algorithms and got a good result.
