ABSTRACT |
Lead aVR ST segment elevation in patients with clinically suspected acute coronary syndrome strongly suggests the possibility of occlusion of the left main coronary artery (LMCA), and stenosis or occlusion in this area can cause severe life-threatening left ventricular dysfunction or malignant arrhythmias. Thus, it could be a sign suggestive of a poor prognosis for patients. In this study, we report on the case of a 67-year-old male who presented to the emergency department with total occlusion of LMCA with ST-segment elevation in only lead aVR, and without ST-segment elevation in other leads. |
