Abstract

Swallow or deglutition syncope is a rare cause of syncope. It occurs due to a vagal reflex while swallowing. We present here a patient with recurrent loss of consciousness after swallowing liquid. He had a 1-month history of concurrent chemoradiotherapy due to non-small cell lung cancer. Electrocardiogram monitoring revealed atrioventricular block with swallowing of beverages. The details of this case suggest that chemoradiotherapy to mediastinum may cause neurogenic swallow syncope.
