[Swallowing-induced supraventricular tachycardias in an asymptomatic young man (author's transl)]. / Tachicardie sopraventricolari da deglutizione in un giovane asintomatico.

Three patterns of swallowing-induced supraventricular tachycardia in an asymptomatic young man are described. The patient had no esophageal disease. The electrophysiologic mechanism of arrhythmias remains speculative. Vagal stimulation produced by swallowing appears to cause tachcardias because atropine (1,5 mg iv) prevents their occurrrence.
