Abstract:The elevation and depression of lead aVR ST segment in electrocardiogram may result from left main coronary artery(LMCA) or its major branches diseases. However, the risk stratification and clinical prognosis of myocardial ischemia or myocardial infarction due to different vascular lesions are rather different from each other. Therefore, it is important to make diagnosis and differential diagnosis of different coronary artery diseases. The changes of ST segment in lead aVR have important clinical significance, the diagnostic and differential diagnostic values of which are higher than any other single lead or multiple leads. This paper reviews on the diagnostic and differential diagnostic significance of the elevation and depression of lead aVR ST segment for different coronary artery diseases, diagnostic criteria and the latest overseas research progress in recent years.
