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.
