Conclusion
Controlled CNA with extra-cardiac vagal stimulation, aiming for the complete elimination of the vagal response in the sinus and atrioventricular nodes, achieves a significantly higher long-term success rate than procedures performed without confirming vagal response elimination via extra-cardiac vagal stimulation. The risk analysis demonstrates that confirmed acute elimination of the vagal response through extra-cardiac vagal stimulation reduces the chances of syncope recurrence by at least fivefold.
