Abstract

Acute coronary syndrome with precordial ST segment elevation is usually related to left anterior descending artery occlusion, although isolated right ventricular infarction has been described as a cause of ST elevation in V1–V3 leads. We present a case of a patient with previous inferior wall infarction and new acute ST elevation myocardial infarction (STEMI) due to proximal right coronary thrombotic occlusion resulting in right ventricular infarction with precordial ST elevation and sinus node dysfunction. The patient was treated with successful rescue angioplasty achieving resolution of acute symptoms and electrocardiographic abnormalities.
