Neurally mediated syncope in association with small cell lung carcinoma

Abstract A 66-year-old woman was admitted to our hospital because of frequent syncopal episodes and for treatment of small cell lung carcinoma. Neurally mediated syncope was diagnosed by the head-up tilt test, which evoked early severe hypotension (after 12 min at the 80-degree tilt position). Treatment of carcinoma by chemotherapy and radiotherapy promptly eliminated the syncopal episodes. This was an unusual case of neurally mediated syncope associated with small cell lung carcinoma.
