Paroxysmal supraventricular tachycardia induced by oral stimulation: a case report and review of swallow-induced dysrhythmias.

We present the case of a 54-year-old man who experienced reproducible paroxysmal supraventricular tachycardia (SVT) with simple oral stimulation. The tachycardia was felt to be focal atrial fibrillation, and the patient was placed on propafenone with good results. There are no previous known cases of this exact condition. However, this may represent a variant of swallow-induced tachycardia. Case reports involving swallow-induced tachycardia with speculated mechanisms and treatments are discussed.
