心电图诊断冠心病已广被采用,但由于缺乏特异性,必须结合一系列临床资料,进行综合判断。随着病理生理进展与心血管造影的应用,冠心病的诊断有了客观诊断依据。本文就心电图中若干异常改变在诊断冠心病中意义作如下讨论。一、左束支前分支传导阻滞(又称左前半阻滞 LAH)解剖组织学证实,左束支在室间隔左面的心内膜下行很快分作两个分支,前分支向前、
ECG diagnosis of coronary heart disease has been widely used, but due to the lack of specificity, we must combine a series of clinical data to make a comprehensive judgment. With the progress of pathophysiology and the application of cardiovascular angiography, the diagnosis of coronary heart disease has the objective diagnosis basis. This article on the ECG abnormal changes in the diagnosis of coronary heart disease in the following discussion. First, the left bundle branch branch block (also known as left anterior block LAH) Anatomical histology confirmed that the left bundle branch in the left ventricular endocardial ventricular septum quickly divided into two branches, the former branch forward,
