Swallowing‐induced atrial tachycardia associated with sympathetic activation: A case report

A 51‐year‐old woman presented with a 5‐year history of a bypass tract of a left posterior septal ablation for atrioventricular reentrant tachycardia (AVRT). Following the procedure, while swallowing even without any water or food, she felt a new onset of palpitations, and swallowing‐induced atrial tachycardia was diagnosed. We report on this patient with tachycardia induced by swallowing who received a comprehensive assessment. The swallowing‐induced atrial tachycardia deriving from the right pulmonary vein was cured by catheter ablation. In our case, the swallowing‐induced atrial tachycardia was connected with the activation of the sympathetic nervous system, which differs from typical reports of a vagal nerve reflex association.
