Key result
DDD pacemaker implantation resolves deglutition syncope in a patient with sick-sinus syndrome.
Why the study?
Deglutition syncope is an uncommon cause of neurally mediated syncope induced by swallowing, with limited clinical reports describing its association with underlying conduction disorders.
Case Report (n=1)
DDD pacemaker implantation successfully resolved recurrent deglutition syncope in a patient with underlying sick-sinus syndrome.

May support DDD pacing in deglutition syncope with sick-sinus syndrome; leaves open need for prospective confirmation.
Deglutition syncope refers to an uncommon cause of neurally mediated syncope induced by swallowing. We briefly review a case of a 66-year-old man who experienced recurrent syncope episodes during ingestion of beverages, mainly water. Our investigations documented several short asymptomatic episodes of asystole and one prolonged complete atrioventricular block of around 15 seconds associated with the syncopal events, during swallowing. Barium x-ray and manometry evaluations revealed only a nonspecific esophageal dysmotility. An underlying sick-sinus syndrome was found on electrophysiologic study. A DDD pacemaker implantation was performed leading to total disappearance of patient's symptoms.

Casella et al. (2009) conducted a case report in Deglutition syncope (n=1). DDD pacemaker implantation was evaluated on Disappearance of symptoms. DDD pacemaker implantation led to the total disappearance of symptoms in a 66-year-old man with deglutition syncope and underlying sick-sinus syndrome.
