Swallow syncope, also called deglutition syncope, is a rare disorder triggered by oral intake. Patients often have underlying esophageal or structural heart disease. In some cases, the condition can be treated conservatively by eliminating predisposing factors. We describe the case of a 65-year-old woman without cardiovascular or esophageal disease who presented after a motor vehicle accident that was attributed to syncope while driving and eating. In the hospital, the patient suddenly lost consciousness while eating solid food; complete heart block without ventricular escape was documented on continuous electrocardiographic monitoring. A dual-chamber permanent pacemaker was placed and completely resolved the symptoms. This case illustrates a high-risk manifestation of swallow syncope: asystole resulting from an exaggerated vago-glossopharyngeal reflex.
