Compare two heart-rhythm strategies after CRT for atrial fibrillation
Part of Heart & circulation clinical trials.
This study looks at whether a “rate control” or “rhythm control” approach works better for people with CRT devices who still have atrial fibrillation. It aims to improve heart failure symptoms and help the heart pace more effectively.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can understand the study, agree to take part, and attend follow-up visits
- You have a CRT device (or are getting one/it is being upgraded) with an atrial lead in place
- Your ECG shows a wide QRS (more than 120 ms), and your heart’s pumping is reduced (EF 35% or less) with heart failure symptoms
- At least 3 months after the CRT procedure, your biventricular pacing is under 95% mainly because of atrial fibrillation
- A doctor recommends AV node ablation as part of your care
- You are expected to live at least 1 year (not less than 1 year)

This study compares two different ablation procedures (treatments that target heart rhythm triggers) for people with atrial fibrillation and reduced heart pumping. It aims to see which approach works best and is safest for improving your heart rhythm when you also have heart failure.
This study compares two treatments for people with atrial fibrillation and heart failure: one is a procedure to fix the irregular heartbeat (AF ablation), and the other involves a different type of pacing for the heart. It aims to find which approach helps you feel better and stay out of the hospital.
This study compares two procedures for people who have both atrial fibrillation (AFib) and heart failure: one that slows the heart's electrical signals (AV node ablation) and one that helps the heart pump in a more coordinated way (cardiac resynchronization). Both are options when medications alone aren't enough, and the goal is to improve symptoms and quality of life.
This study compares two ways to place a pacemaker lead in the heart for people who have heart failure and a type of irregular heartbeat called atrial fibrillation. The goal is to see which pacing method helps the heart pump blood better.
This trial studies whether a strategy to regularize (control) heart rate can improve outcomes in people who have permanent atrial fibrillation and heart failure. It focuses on people with recent heart-failure hospitalization and checks several heart, kidney, and health-condition limits to keep the study safe.
This trial tests whether a catheter procedure that treats atrial fibrillation works better than standard care for people with heart failure with preserved ejection fraction. It aims to improve heart rhythm symptoms and overall outcomes compared with conventional treatment.
