ST segment elevation in lead aVR: what to expect from this orphan?
Standard 12-lead electrocardiography is used to diagnose acute myocardial infarctions in patient presenting with ST elevation. The specificity of ST segment elevation for the corresponding area is more than 90 percent. It has been suggested that ST-segment elevation in lead aVR may indicate left main disease. We will present a patient who had an ST segment elevation in this lead. We will review the current data about this finding, as well as the significance of ST segment elevation in other leads.
