title: Swallow syncope.
abstract: Swallow syncope is an often misdiagnosed rare disorder due to enhanced vagal tone during eating in patients with underlying esophageal and/or cardiac abnormalities. We present three cases of this disorder, one related to digitalis toxicity and the other two with diffuse esophageal spasm. The investigation, differential diagnosis, prognosis and management of swallow syncope are discussed.
