Abstract

A patient who presented with acute inferior-right ventricular (RV) ST-segment elevation (STE) myocardial infarction (MI) is described. Coronary angiography showed a mid-right coronary artery (RCA) occlusion and high-grade proximal left anterior descending (LAD) artery stenoses. Electrocardiography (ECG) after stent angioplasty to the RCA showed new STE in leads V1-V6. Whereas STE pattern recognition was misleading, ECG analysis using vector concepts enabled exclusion of anterior MI due to proximal LAD artery occlusion and recognition of the RV origin of this ECG picture. The ability of the ECG to "capture" RV dilation that enabled the manifestation of this ECG picture is highlighted. Copyright © 2019 Elsevier Inc. All rights reserved.
