Abstract:

Use wavelet transform to identify the idiographic shape of QRS,P,T of Electrocardiograph(ECG), and obtain the shape ,beginning,end of wave and relevant parameter. The expert system of ECG diagnosis was set up on the basis of characteristic parameter, in which a new fuzzy inference method was used to develop the fuzzy expert system based on experience and specialty knowledge of experts. This method was tested using VC++6.0. The test shows that this system can automatically diagnose the result of ECG well and truly.

摘要： 利用小波变换技术对心电图的QRS 波、P 波、T 波的具体形态进行识别, 由此得到各个波的形态、起
点、终点的位置及相应的参数值。并在得到特征参数的基础上构建了心电图诊断专家系统, 它是以领域专家的理论
知识和经验知识为基础, 采用一种新的模糊推理方法建立模糊专家系统。采用VC++6 .0 对该方法进行检测, 结果
显示该系统能较准确对心电图进行自动分类诊断。
