Summary: A 51-year-old male with swallow syncope is reported. He did not have organic esophageal disease, organic heart disease or neurologic disease. Holter monitoring showed multiple episodes of asymptomatic paroxysmal atrioventricular block and sinus bradycardia during meals. Inflation of a balloon positioned in the lower esophagus reproducibly induced atrioventricular block, sinus bradycardia and hypotension. Atropine sulfate 0.5 mg prevented atrioventricular block and hypotension. He complained of fainting and syncope with dysphagic sensation only during hasty eating. We advised him to eat slowly, and he has been followed up without anticholinergic drugs or cardiac pacing. He has not complained of fainting since discharge from our hospital.

Key words: Swallow syncope, Atrioventricular block, Sinus bradycardia
