摘要
近年来,心脑血管患病数超过2.9亿,死亡率仍处在上升阶段,防治心血管病刻不容缓,心电技术尤为重要。临床诊断通常采用12导联系统,同时配合可视化技术可以较为直观地反映心脏的信号传播活动。利用12导联ECG可视化技术分析心电特征对于不同疾病的差异程度,首先利用GQRS-极值法对心电信号进行波峰识别,其次将提取到的心电特征进行统计分析,最后通过信息增益的方法分析各特征之间的差异。对于疾病异常情况,可以通过本文的心电特征可视化分析技术快速反映心脏不同部位的病变程度。
In recent years,the number of cardiovascular and cerebrovascular diseases has exceeded 290 million,and the mortality rate is still in the rising stage.The prevention and treatment of cardiovascular diseases cannot be delayed.Therefore,electrocardiography is particularly important.Clinical diagnosis usually adopts 12-lead system,together with visualization technology can more intuitively reflect the heart's signal propagation activity.In this paper,the 12-lead ECG visualization technology is used to analyze the degree of difference in ECG characteristics for different diseases.First,the GQRS-extreme method is used to identify the peaks of the ECG signal,followed by statistical analysis of the extracted ECG characteristics,and finally the information gain The method analyzes the differences between features.For abnormal conditions of the disease,the visual analysis technology of ECG characteristics in this paper can quickly reflect the degree of lesions in different parts of the heart.
