Key result
Slow pathway ablation achieves complete symptom resolution in swallowing-induced AVNRT.
Why the study?
Swallowing-induced atrioventricular nodal reentrant tachycardia is a rare cause of recurrent palpitations with limited therapeutic reports.

Swallow-induced right atrial SVT warrants clinical recognition; leaves open mechanistic and therapeutic insights pending larger cohorts.
We describe two patients who presented with a history of recurrent palpitations on swallowing of solid food. The event-recorder and Holter monitoring documented episodic supraventricular tachycardia (SVT) initiated by atrial premature contractions (APCs). During electrophysiological study (EPS), swallowing of solid food consistently induced APCs and their activation sequence, morphology of P wave were suggestive of their right atrial origin in them. Drug challenge did not affect the APC onset during the swallowing. During EPS, slow-fast variety of atrioventricular nodal reentrant tachycardia (AVNRT) was induced and successful radiofrequency (RF) catheter ablation of slow pathway resulted in total relief of their symptoms.

Satish et al. (2005) conducted a case report in Swallowing-induced atrioventricular nodal reentrant tachycardia (n=2). Radiofrequency (RF) catheter ablation of slow pathway was evaluated on Relief of symptoms. Radiofrequency catheter ablation of the slow pathway resulted in total relief of symptoms in two patients with swallowing-induced atrioventricular nodal reentrant tachycardia.
