Acute Myocardial Infarction with Elevated ST-segment Only in Lead aVR

초록

Lead aVR ST segment elevation in patients with clinicallysuspected acute coronary syndrome strongly suggests thepossibility of occlusion of the left main coronary artery(LMCA), and stenosis or occlusion in this area can causesevere life-threatening left ventricular dysfunction or malignantarrhythmias. Thus, it could be a sign suggestive of apoor prognosis for patients. In this study, we report on thecase of a 67-year-old male who presented to the emergencydepartment with total occlusion of LMCA with STsegmentelevation in only lead aVR, and without ST-segmentelevation in other leads.
