Right bundle branch block, persistent ST-segment elevation in V1-V3 and sudden cardiac death: always a distinct syndrome?
Right bundle branch block, persistent ST segment elevation in right precordial leads and sudden cardiac death, unexplainable by currently known disease, define a new distinct clinical and electrocardiographic syndrome. This report describe a patient with these features, whose physical examination, echocardiography, chest computed tomography and right ventricular angiography were normal. However, despite the negativity of these examinations, cardiac nuclear magnetic resonance allowed the identification of right ventricular dysplasia. Thus, right ventricular dysplasia should be considered in the differential diagnosis of the syndrome characterized by right bundle branch block, persistent ST segment elevation and sudden cardiac death.
