Proximal RCA occlusion producing anterior ST segment elevation, Q waves, and T wave inversion

Abstract

An ST segment elevation myocardial infarction (STEMI) that produces anterior ST segment elevation (STE) is typically caused by acute occlusion of the left anterior descending (LAD) artery. Anterior STE, however, may also be caused by acute occlusion of either the proximal right coronary artery (RCA) or the right ventricular marginal branch (RVB). It has been thought that, in contrast to occlusions of the LAD, proximal RCA/RVB occlusion rarely causes Q waves in the right precordial leads. We present a case where a proximal RCA occlusion produced not only anterior STE, but also anterior T wave inversions and anterior Q waves.

Keywords: Anterior wall myocardial infarction; Electrocardiography; Myocardial infarction/diagnosis; Right ventricle infarction.
