Isolated right ventricular infarction: a diagnostic challenge

Right ventricular involvement during myocardial infarction of the diaphragmatic and posterior wall of the left ventricle is not an infrequent complication, but isolated right ventricular infarction is rare. We report a case of rupture of the anterior wall of right ventricle and tamponade due to infarction at this site. The lack of characteristic clinical and electrocardiographic findings made the isolated right ventricular infarction a diagnostic challenge.
