Electrocardiographic changes in acute myocardial infarction with acute occlusion of all triple coronary arteries

Abstract

The 66-year-old woman was diagnosed with “acute myocardial infarction” due to acute triple vessel occlusion based on clinical symptoms, laboratory examination, and coronary angiography (CAG), but her ECG showed ST-segment depression in leads aVR and aVL, in addition to ST-segment elevation in a wide range of leads (V1–V9, V3R–V5R, II, III, and aVF). Thus, a perfect explanation with the existing theory is difficult, and only the case is presented here.
