Swallow Syncope

Swallow syncope associated with complete atrioventricular block and vasovagal syncope.

A 21 year old man presented with multiple, recurrent episodes of complete atrioventricular (AV) block associated with swallowing. Electrophysiological study revealed an AV block with swallowing of carbonated beverages and balloon inflation in the lower oesophagus. Evaluation did not demonstrate any underlying oesophageal or cardiac disease, and the AV block was not induced after intravenous atr...

Swallow syncope: a case report and review of the literature.

Swallow or deglutition syncope is a relatively rare syndrome. It is a vagally mediated syncope induced by swallowing. Swallow syncope may occur in all age groups and, when diagnosed, is treatable. A woman, aged 60 years, presented with an episode of a syncopal attack associated with swallowing a sandwich. She had a 6-month history of recurrent episodes of lightheadedness while eating solid food...

A Case of Swallow Syncope Associated With Cold Beverage Ingestion

Swallow syncope (also known as deglutition syncope) is a relatively rare type of syncope that is treatable if diagnosed correctly. We report a case of a 39-year-old man with recurrent swallow syncope. The patient did not have structural heart disease. He developed a complete atrioventricular block upon drinking a cold beverage (Chilsung cider) while undergoing a repeated head-up tilt test. The ...

Thirty years of blackouts: a case report of swallow syncope

Deglutition syncope has been demonstrated in isolated case reports, the first being described over 50 years ago. It is thought to be caused by a hypersensitive vagotonic reflex in response to esophageal dilation after swallowing. It can cause syncope due to complete atrioventricular (AV) block and acute reduction of cardiac output. Although rare, its lethality is worthy of discussion, as early ...
