Cardioneuroablation for carotid sinus syndrome mediated by complete atrioventricular block.

Carotid sinus syndrome (CSS) is a rare condition leading to recurrent syncope. Permanent pacemaker implantation is the mainstay treatment of cardioinhibitory CSS. In this report, we present a CSS patient with reproducible atrioventricular block during carotid massage, who was treated with cardioneuroablation.
