Swallowing triggers AV block in a rare case of deglutition syncope.
This case report highlights swallowing-induced atrioventricular block as a rare etiology for syncope.
Swallowing-induced AV block merits consideration in unexplained syncope; leaves open questions on prevalence and management strategies.
One of the rare causes of syncope is "swallowing syncope," or "deglutition syncope." We have reported a case of atrioventricular block induced by swallowing.
