Key result
Cold beverage ingestion reproducibly triggers complete AV block and swallow syncope in a 39-year-old man.
Why the study?
Swallow syncope is a relatively rare and treatable type of syncope that requires correct diagnosis for effective management.
Case Report (n=1)
Swallow syncope can be triggered by cold beverage ingestion and successfully managed by avoiding the trigger.

Cold beverage may trigger swallow syncope with AV block; single case leaves open generalizability and optimal management.
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 patient was advised to avoid cold beverages and has been symptom free for 5 months.

Kim et al. (2012) conducted a case report in Swallow syncope (n=1). Cold beverage ingestion was evaluated on Occurrence of atrioventricular block and syncope symptoms. Ingestion of a cold beverage during a head-up tilt test reproducibly induced a transient complete atrioventricular block and swallow syncope in a 39-year-old man without structural heart disease.
