Exercise and heart function before and after heart rhythm procedures
Part of Heart & circulation clinical trials.
This study looks at how well your heart performs during exercise before and after you have a procedure to manage your atrial fibrillation (either a pacemaker with ablation or cardioversion). The goal is to see if these treatments improve your heart's function and exercise ability.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have persistent or permanent atrial fibrillation (an irregular heart rhythm that doesn't go away on its own).
- You have heart failure that causes symptoms like shortness of breath or fatigue (NYHA class II to IV), despite taking medications.
- Your heart rate is currently well controlled (not too fast).
- You are able to walk on a treadmill or ride a bike for a stress test.
- You are already scheduled to have either a pace and ablate procedure (a pacemaker plus a procedure to fix the heart's electrical signals) or a cardioversion (a shock to restore normal rhythm).

Other trials that look related to this one.
This trial is testing whether a structured exercise program (combining cardio and strength training) can help people who have already had a procedure to treat atrial fibrillation. It aims to see if this type of training can improve heart health and quality of life.
This study tests whether a short exercise and education program before a first-time ablation for atrial fibrillation improves your recovery and heart fitness. It's for people with mild or no heart failure symptoms and a well-pumping heart.
This study tests if starting a supervised exercise program can help older adults with both atrial fibrillation and a type of heart failure called HFpEF feel better and have a better quality of life. You'll be asked to join exercise sessions and have regular check-ins to see how you're doing.
This study tests whether doing a short cycling exercise right before a heart shock procedure (called electrical cardioversion) can make the procedure more effective at restoring a normal heartbeat. If successful, it could simplify treatment for people with persistent atrial fibrillation.
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 trial tests whether a procedure called electrical cardioversion (a controlled shock to reset your heart rhythm) can help explain and possibly improve symptoms of atrial fibrillation and heart failure. If you qualify, you'll receive this procedure and your symptoms will be closely monitored.
