Abstract

A 71-year old female patient with supraventricular and ventricular arrhythmias presented to the Medical Care Unit. Her ECG was in sinus rhythm, incomplete right bundle branch block with right precordial QRS prolongation suspicious for arrhythmogenic right ventricular cardiomyopathy. The amplitude of the inverted S wave in lead V1 was more than 2mm, in lead aVR a deep Q wave, a small R wave and in inverted T wave with an amplitude of 3mm were present. A cardiac MRI was performed with no obvious findings of arrhythmogenic right ventricular cardiomyopathy, no RV dilatation, but myocardial edema at the apex of the ventricle, apical hypokinesia, and very small pericardial effusions along the right ventricle and right atrium. A gadolinium scan revealed abnormalities at inferior site of the left ventricle. The diagnosis was subacute peri-myocarditis of the right ventricle.
