Key result
Treatment with verapamil /day reduced symptoms of swallowing-induced paroxysmal supraventricular tachycardia despite an insignificant decrease in the arrhythmia observed on Holter monitoring.
Why the study?
Swallowing-induced paroxysmal supraventricular tachycardia without esophageal or heart disease is a rare arrhythmia requiring detailed electrophysiological characterization.

A 54-year-old man had palpitations on swallowing without any esophageal or heart disease. Electrophysiological findings, including an A wave in the high right atrial leads appearing prior to the A wave on His bundle electrogram, revealed that the arrhythmia was paroxysmal supraventricular tachycardia originating in an ectopic focus of the atrium with intraventricular aberration. Treatment with verapamil, 120 mg/day, reduced his symptoms in spite of an insignificant decrease in the arrhythmia observed with Holter dynamic electrocardiography.

Terasaka et al. (1987) conducted a case report in Swallowing-induced Paroxysmal Supraventricular Tachycardia (n=1). Verapamil was evaluated on Symptom reduction. Treatment with verapamil /day reduced symptoms of swallowing-induced paroxysmal supraventricular tachycardia despite an insignificant decrease in the arrhythmia observed on Holter monitoring.
