[Sudden cardiac death from unrecognized cardiac sarcoidosis]

Sarcoidosis is a systemic disease of young adults. Cardiac involvement is rarely diagnosed clinically. It presents with arrhythmias, conduction disorders, increasing myocardial insufficiency, or sudden death. We report a 42-year-old man with cardiac conduction disturbances of unknown cause who died of sudden cardiac death. Sarcoidosis with prominent cardiac involvement was diagnosed only at autopsy. Cardiac sarcoidosis should be considered in young patients with unexplained conduction disorders.
