ST segment elevation in leads V₁ to V₃ due to isolated right ventricular branch occlusion during primary right coronary angioplasty

Abstract

It is rare to observe ST elevation in anterior derivations caused by isolated right ventricular branch occlusion. We described the case with acute inferior and right ventricular myocardial infarction (MI) who developed ST segment elevation in precordial leads V(1) to V(3) due to isolated right ventricular branch occlusion during primary right coronary angioplasty.
