| ［摘要］ 冠状动脉粥样硬化性心脏病严重威胁人类生命健康，据世界卫生组织（WHO）资料统计表明，全球因冠心病死亡的人数每年都居死因的首位。传统的心电图对心肌梗死、心肌缺血的定位诊断未提及aVR导联的诊断价值，故临床上常忽略了aVR导联的作用。新近研究表明，心电图aVR导联ST段的抬高或者压低,常常提示有严重的冠状动脉左主干病变、前降支近段病变或者三支病变,预后较差,需要积极干预，而且aVR导联ST段的改变对判断心肌梗死、预测冠脉病变范围、严重程度及短期预后均有重要的意义。该文对心电图aVR导联ST段改变在急性冠脉综合征诊断中作用的研究进展作一简要的综述。 |

| Abstract: |
| ［Abstract］ Coronary atherosclerotic heart disease threatens human health seriously. According to statistics from the World Health Organization, coronary heart disease is the first leading cause of death globally each year. The value of aVR lead is not mentioned in the diagnosis of myocardial infarction and myocardial ischemia in conventional electrocardiogram(ECG), therefore it is often ignored in clinics. Recent researches show that ST segment elevation or ST segment depression in aVR lead indicates severe left main coronary artery lesions or left anterior descending proximal lesions or three vessels lesions, and poorer prognosis. ST segment changes in aVR lead have significant clinical value for diagnosing and evaluating myocardial infarction, including the scope of coronary artery lesion and severity, and short-term prognosis. In this paper, the research progress of the changes of ST segments in aVR lead in diagnosis of acute coronary syndrome(ACS) is reviewed. |
