Does propafenone prevent deglutition-induced atrial tachycardia and atrial fibrillation in a 46-year-old woman?
Propafenone successfully treated a rare case of deglutition-induced atrial tachycardia and atrial fibrillation, the first reported case of both arrhythmias occurring in the same patient.
Propafenone may control deglutition-induced atrial tachyarrhythmias in rare cases; leaves open confirmation in prospective studies.
Deglutition induced supraventricular tachycardia is an uncommon condition postulated to be a vagally mediated phenomenon due to mechanical stimulation. Patients usually present with mild symptoms or may have severe debilitating symptoms. Treatment with Class I agents, beta blockers, calcium channel blockers, amiodarone and radiofrquency catheter ablation has shown to be successful in the majority of reported cases. We report the case of a 46-year-old healthy woman presenting with palpitations on swallowing that was documented to be transient atrial tachycardia with aberrant ventricular conduction as well as transient atrial fibrillation. She was successfully treated with propafenone with no induction of swallowing-induced tachycardia after treatment. This is also the first case to show swallowing-induced atrial tachycardia and atrial fibrillation in the same patient.

Kanjwal et al. (2007) conducted a case report in Deglutition induced atrial tachycardia and atrial fibrillation (n=1). Propafenone was evaluated on Induction of swallowing-induced tachycardia after treatment. Propafenone successfully treated a 46-year-old woman with deglutition-induced transient atrial tachycardia and atrial fibrillation, with no induction of tachycardia after treatment.
