“…In most patients with deglutition tachyarrhythmias, atrial pacing does not trigger similar arrhythmias 710-14 In most cases enhanced or triggered automaticity is suggested as the mechanism for deglutition atrial tachyarrhythmias because of demonstration of warm up and cool down phenomena and by continuation of the tachycardia when there is atrioventricular block 1014 In a few patients atrial fibrillation or atrial flutter was the sole detected tachyarrhythmias 15.…”

Three cases with supraventricular tachyarrhythmias related to oesophageal transit are reported. A 61 year old man had episodes of atrial tachycardia on each swallow of food but not liquid; this has been reported only rarely. A 55 year old man had atrial fibrillation initiated by drinking ice cold beverages; this has not been described previously although atrial tachycardia triggered by drinking ice cold beverages has been described once. A 68 year old man had supraventricular tachycardia initiated by belching; this has not been described previously. These cases illustrate the diversity of atrial tachyarrhythmias that can be precipitated by oesophageal stimulation and suggest that what is regarded as a very rare phenomenon may be found more commonly when sought.

“…Even though we could clearly demonstrate that the presence of solid food in the esophagus either at carinal or supracarinal level initiated the APCs, the exact underlying mechanism of induction of these APCs was obscure in our patients. The mapping in these cases has shown that the arrhythmias originated from LA 8 or RA 9 . In the study patients also, the activation sequence and morphology of APCs were suggestive of their RA origin, even though we did not map the LA directly.…”

Radiofrequency Catheter Ablation Therapy of Swallowing‐Induced Atrioventricular Nodal Reentrant Tachycardia: Report of Two Cases

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.

“…Increased automaticity has been shown to be the predominant mechanism responsible for swallowing‐induced tachyarrhythmias 8,9 . Vagal stimulation which is well known to cause bradycardia has been implicated in the development of deglutition‐induced tachyarrhythmias 12 .…”

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.
