Pacemaker versus ablation therapy for repeated fainting spells

This trial is testing two different treatments for a type of fainting spell caused by an overactive nerve reflex in your heart and body. You would be randomly assigned to receive either a dual-chamber pacemaker (a small device implanted under your skin to regulate your heartbeat) or cardioneuroablation (a catheter-based procedure that uses targeted heat to calm overactive nerve pathways in your heart). Both treatments aim to prevent the sudden drops in heart rate and blood pressure that trigger your fainting episodes.

While pacemakers have been used for years to help people with severe fainting spells, a newer technique called cardioneuroablation has shown promise in small studies and may offer an alternative without implanting a device. This trial compares both approaches fairly to see which works better for preventing fainting and improving quality of life.
