title: Asystolic arrest as a presentation of sarcoidosis.
abstract: A 41-year-old man who presented with a history of sudden loss of consciousness suffered two further episodes during which asystole was documented. Subsequent investigations included exercise stress testing, thallium scintigraphy, electrophysiological studies, CT-scan of chest, Kveim test and a gallium-67 scan, which led to a presumptive diagnosis of averted sudden death as a first presentation of sarcoidosis with primary cardiac involvement.
