摘要
Abstract
Severe coronary artery diseases include acute complete or subtotal occlusion of left main coronary artery(LMCA)and 3-vessel disease(3-vd).Although the patients with acute com-plete occlusion of LMCA rarely arrive to hospital alive,the specificity and accuracy rate of ST seg-ment elevation in lead aVR are both above 80%.For the patients with acute subtotal occlusion of LMCA and 3-vd,its diagnostic value is higher than that of any other single lead or multiple ones. The higher the amplitude of ST segment elevation in lead aVR is and the longer the duration is,the more serious the patient's condition is.This paper reviews the diagnostic criteria of ST segment ele-vation in lead aVR,electrophysiological mechanism and overseas research progress.关键词
