Swallowing-induced atrial tachycardia: A rare demonstration on fluoroscopic esophagram.

Background: Swallowing-associated arrhythmias are rare and most commonly present as atrial tachycardias.

Methods: We present a case of a 45-year-old female who experienced frequent episodes of palpitations and dyspnea occurring immediately after swallowing solid food. She was noted to have atrial tachycardia with deglutition that was recorded on the 12-lead electrocardiogram. She underwent fluoroscopic esophagram that demonstrated atrial tachycardia as the barium passed through the distal esophagus and gastroesophageal junction.

Conclusion: Swallowing induced arrhythmias occur rarely and can be confirmed by EKG obtained during deglutition. Gastroesophageal evaluation is required to rule out primary esophageal disorders. Treatment of such arrhythmias is required if symptoms are intractable and can include pharmacotherapy and radiofrequency ablation.
