Swallowing-induced atrial tachycardia associated with sympathetic activation: A case report.
2020
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.
