Freezing vs. Radiofrequency for Slow Heart Rate
Part of Brain & nervous system, Heart & circulation clinical trials.
This trial compares two procedures to treat very slow heart rates without needing a pacemaker. One uses freezing (cryoablation) and the other uses radiofrequency energy to target nerves that control heart rate.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 60 years old.
- You have a slow heart rate (bradycardia) that causes symptoms like fainting, dizziness, or pauses in your heartbeat.
- Your heart rate must increase by at least 25% or above 90 beats per minute when given atropine or during exercise.
- You do not have a pacemaker or similar device already implanted.
- Your slow heart rate is not caused by medications, thyroid problems, sleep apnea, or high potassium levels.

This study compares a procedure called cardioneuroablation with staying on permanent pacing in people who have symptoms from a slow heart rate. It aims to see which approach works better and is safer for reducing symptoms related to sinus node or heart conduction problems.
This test uses a procedure to ablate (destroy) specific nerves in the heart that may be causing your heart to beat too slowly. The goal is to help your heart speed up naturally when needed, so you may avoid needing a permanent pacemaker.
This study tests a procedure called cardioneuroablation, which uses targeted heat (radiofrequency) to calm overactive nerves that cause your heart to beat too slowly and make you faint. The goal is to stop severe fainting spells in people with reflex syncope who haven't gotten better with other treatments.
This study tests if a procedure called cardioneuroablation can help people who faint or feel like they're about to faint due to a slow heart rate. The treatment targets the nerves around the heart to improve heart rate control and exercise capacity.
This trial tests a procedure called cardioneuroablation to treat severe fainting (reflex syncope) that hasn't been helped by other treatments. The goal is to see if it reduces fainting without causing dangerous heart rhythm problems.
This study compares two treatments for specific “AV block” heart rhythm problems: a pacemaker versus a procedure called cardioneuroablation. The goal is to see which approach works better for preventing symptoms like fainting or slow heart rates.
