A case of cardiac sarcoidosis: significance of ventricular tachycardia originating from the septum.
A 65-year-old woman was admitted for assessment of recurrent tachycardia. Cross-sectional echocardiography showed that the anterobasal portion of the ventricular septum was thin and dyskinetic. An electrophysiologic study revealed ventricular tachycardia, during which marked fragmented potentials could be obtained from the anterior septal aspect of the right ventricle. The site of earliest activation was in the vicinity of the His bundle. A diagnosis of cardiac sarcoidosis was made by based on endomyocardial biopsy combined with the clinical manifestations. Ventricular tachycardia originating from the anterior septum may be an indicator of underlying cardiac sarcoidosis.
