Key result
Permanent pacemaker implantation resolves swallow-induced syncope and ventricular asystole in permanent atrial fibrillation.
Why the study?
Deglutition syncope is a situational syncope diagnosed only by detailed history and its association with ventricular asystole in permanent atrial fibrillation is rarely reported.
Case Report (n=1)
Permanent pacemaker implantation can successfully treat deglutition syncope associated with ventricular asystole in patients with permanent atrial fibrillation.

May support pacing for deglutition syncope with documented asystole; leaves open incidence, mechanisms, and management guidelines.
Deglutition syncope is a situational syncope that is diagnosed only by a detailed history. We report deglutition syncope in a 62-year-old man, who had permanent atrial fibrillation. The patient had no structural or functional abnormalities of the esophagus. During syncopal attacks, his electrocardiography showed ventricular asystole that was sustained for 12 seconds. The patient was successfully treated by implantation of a permanent pacemaker.

Lee et al. (2010) conducted a case report in Deglutition syncope with permanent atrial fibrillation (n=1). Permanent pacemaker implantation was evaluated on Prevention of syncope and ventricular asystole. Implantation of a permanent pacemaker successfully prevented further episodes of ventricular asystole and syncope triggered by swallowing cold beverages in a patient with permanent atrial fibrillation.
