Background
Cardioneuroablation (CNA) is a novel therapeutic approach for functional
bradyarrhythmias, specifically neurocardiogenic syncope or atrial
fibrillation, achieved through endocardial radiofrequency catheter
ablation of vagal innervation, obviating the need for pacemaker
implantation. Originating in the nineties, the first series of CNA
procedures was published in 2005. Extra-cardiac vagal stimulation (ECVS)
is employed as a direct method for stepwise denervation control during
CNA.
