Deglutition syncope, also known as swallow syncope, is a neurally mediated reflex syndrome. The common intervention of the heart, esophagus, and stomach by the vagus nerve is central to its pathogenesis, whereby swallowing causes inhibition of the cardiac conduction system. It is most commonly associated with disorders of the esophagus, both organic and functional. Herein we describe the case of a 48-year-old man presenting with transient syncopal episodes that occurred while eating caused by an intrathoracic stomach due to a hiatal hernia.
