Summary

This study looks at a new procedure called cardioneuroablation for people with severe fainting spells. The procedure uses radio waves to target specific nerve clusters in the heart. The study will compare three methods to find these nerve clusters: electrical signals, CT scans, and ultrasound. The goal is to see which method works best to guide the procedure and improve results for patients.
