Abstract

Swallowing-induced tachycardia is a rare phenomenon, with only 50 cases documented worldwide. We present a unique case of an adolescent with hypertrophic cardiomyopathy (HCM) who presented with palpitations and a near syncopal episode. The patient was found to have a swallowing-induced atrial tachycardia. He underwent radiofrequency isolation of the right superior pulmonary vein and ablation of the right anterior ganglionated plexus, which led to a resolution of his symptoms. This case highlights the possible association between HCM and autonomic instability as potential aetiological mechanism for the tachycardia.
