Abstract:
Deglutition syncope (DS) is a rare, neurally-mediated syncopal syndrome arising from an aberrant vagotonic reflex during swallow-associated esophageal dilation. Its association with gastroesophageal disorders often prompts gastroenterology consultation. An 89-year-old man with recent dysphagia and otalgia was admitted after a syncopal episode occurred while eating. Esophageal imaging and endoscopy demonstrated no causative abnormalities. Maxillofacial imaging revealed chronic sinusitis and mastoiditis. Telemetry monitoring demonstrated high-grade atrioventricular block and pause associated with swallowing. His symptoms and swallow-associated arrhythmia resolved after dual chamber pacemaker implantation. DS is highly treatable once identified and multidisciplinary coordination is helpful in optimizing outcomes and avoiding superfluous testing.
