Cardioneuroablation for Neurocardiogenic Syncope

CNA was proposed for treating several conditions related to vagal hyperactivity:[2] reflex and/or functional bradyarrhythmias and vagal atrial fibrillation (AF). In the nineties, was observed that ablation of AF-Nests (AFN)[3], a kind of atrial myocardium with disconnected cells, resulted in vagal denervation, reducing drastically de heart rate variability and making the heart nonresponsive to atropine[2,4]. Therefore, in 2005 was published the first study describing the CNA by ablating the AFN, mainly the ones overlapping the main GPs.
