Dangerous noodle: A case of swallowing syncope and a review of 122 cases from the literature

Abstract

Swallowing syncope is a rare medical condition. Even though it has been known as a neurally mediated syncope, the definitive mechanism of this condition remains unclear. We show in this study an additional case of swallowing syncope and review the 122 reported cases from the literature. A 47-year-old Japanese man had been suffering from recurrent syncopal attacks, when he fainted immediately after swallowing. Holter electrocardiogram monitoring demonstrated a sinus pause (maximum R-R interval of 3.8 seconds) after he swallowed a noodle quickly. A permanent pacemaker was implanted because the frequency of syncope increased.

Keywords: deglutition; permanent pacemaker; sinus arrest; situational syncope; swallowing syncope.
