JACC Case Rep. 2024 Jan 9;29(4):102185. doi: 10.1016/j.jaccas.2023.102185. eCollection 2024 Feb 21.

Abstract

Hypervagotonic sinus node dysfunction (SND) is a form of SND with sinus bradycardia caused by enhanced vagal tone. Indirect proof of hypervagotonia as the mechanism can be inferred from resolution of bradycardia following atropine infusion. In symptomatic patients, pacemaker implantation is recommended. We describe cardioneuroablation as a treatment for hypervagotonic SND.

Keywords: cardioneuroablation; hypervagotonia; sinus node dysfunction.
