An ST-segment elevation in precordial Electrocardiography (ECG) leads is-almost always-characteristic of acute Left Anterior Descending (LAD) Coronary Artery occlusion, leading to ventricular wall infarction and eventually resulting in Anterior, Anteroseptal or Anterolateral ST-segment Elevation Myocardial Infarction (STEMI). However, it is rarely observed, in patients with proximal right coronary artery occlusion and is thought to signify right ventricular myocardial infarction and even associated with isolated total occlusion of Right Ventricular branch. In the present report, we present a case series of ST-segment elevation in the precordial leads as a result of either proximal Right Coronary Artery or Ventricular branch occlusion
