Using electrical shock to restore normal heart rhythm after surgery
Part of Heart & circulation clinical trials.
This study looks at whether giving an electrical shock (cardioversion) right after heart surgery can help people with long-lasting atrial fibrillation keep a normal heartbeat. It may help guide future treatment decisions for patients who have not gotten better with medication.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had atrial fibrillation (a fast, irregular heartbeat) that has lasted for 6 months or longer and medication has not helped.
- Your left atrium (a heart chamber) must be smaller than 55 mm in size, with a volume under 130 ml, and a volume index under 55 ml/m2.
- You must be willing to sign a consent form.
- You cannot have other causes for your atrial fibrillation, like thyroid problems or heart inflammation.
- You cannot have had previous heart procedures like MAZE surgery or ablation, and you cannot need heart bypass or valve surgery.
- You must not have a blood clot in your left atrium, and you must be able to take blood thinners.
- Your body mass index (BMI) must be less than 40.

This trial tests a special defibrillation technique that uses two shocks to reset the heart's rhythm in people with persistent atrial fibrillation. It aims to help patients regain a normal heartbeat without the need for more invasive procedures.
This trial tests whether using a specific “shock energy” during electrical cardioversion works safely and effectively for people with persistent atrial fibrillation. You might be eligible if your cardioversion is planned (not an emergency) and your doctors determine you can safely take blood thinners.
This study looks at how a heart rhythm procedure (cardioversion) affects quality of life in people with persistent atrial fibrillation (AF). It may help you understand whether a specific approach can improve day-to-day symptoms and well-being after treatment.
This trial looks at whether a special heart rhythm treatment called “ablation” works well when done during certain heart operations. It may help reduce atrial fibrillation (AF) symptoms or future abnormal rhythm episodes for people who are already having surgery.
This study tests whether two different positions of the electrodes (pads) used for an electrical shock work equally well for people with atrial fibrillation or flutter. It may help improve how safely and effectively the shock restores a normal rhythm.
This trial tests whether a medicine called amiodarone can help prevent an irregular heartbeat (atrial fibrillation) that sometimes happens after heart surgery. If you are having heart surgery (other than bypass surgery) and have a normal heart rhythm, this study might help you recover with fewer heart rhythm problems.
