Catheter ablation for slow heart rate study
Part of Brain & nervous system clinical trials.
This study tests a catheter procedure to treat a slow heart rate (bradycardia) that causes symptoms like dizziness or fainting. It may be an option for people who haven't had a pacemaker and whose heart can still speed up with medication.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 65 years old.
- You have symptoms from a slow heart rate, such as fainting, dizziness, or extreme tiredness.
- Your average heart rate is less than 50 beats per minute or you have pauses longer than 3 seconds during the day.
- Your heart can speed up by at least 25% after a medication test (atropine test).
- You have not had a pacemaker or similar heart device placed.
- You are not using heart rhythm medications that affect heart rate.

This study tests whether heart catheter ablation can safely stop repeated dangerous heart rhythms in people with heart disease. It may help those who are having frequent episodes that cause very low blood pressure.
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 for people whose fainting or very slow heartbeat doesn't improve with other treatments. If you are under 60, have no other major heart conditions, and have not had ablation before, it might be an option to reduce or stop your fainting spells.
This trial studies treatments for a type of fainting caused by the body’s reflex slowing the heart. It compares a permanent pacemaker with a procedure called cardiac nerve ablation to see which helps prevent fainting and improves quality of life.
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.
