Heart remodeling after pulsed field ablation for persistent atrial fibrillation
This study looks at how a new type of heart procedure, called pulsed field ablation, affects the heart's structure in people with persistent atrial fibrillation. It may help doctors understand if this treatment improves heart function over time.
TaipeiAges 18 years+ - NCT06675383Recruiting
Screening for atrial fibrillation after stroke
This trial tests whether extended monitoring can detect hidden atrial fibrillation (an irregular heartbeat) in people who have had a stroke. If found, treatment can help prevent another stroke.
Sogneprest Munthe-kaas Vei 100, GjettumAges 18 years+ - NCT06519747Recruiting
Detecting irregular heartbeat after non-heart surgery
This trial uses a monitoring device to check for a common but often overlooked irregular heartbeat (atrial fibrillation) after non-cardiac surgery. The goal is to detect and treat it early to prevent complications like stroke.
Hamilton, OntarioAges 18–120 - NCT06698159Recruiting
Wider pulmonary vein isolation in AFib ablation with single-shot cryoablation
This study tests a new approach to a common procedure for atrial fibrillation (AFib) called pulmonary vein isolation. It uses a single-shot cryoablation technique to treat people with paroxysmal or persistent AFib.
Pozzilli, IserniaAges 18 years+ - NCT07626411RecruitingPhase 3
Blood Thinner Study for Irregular Heartbeat
This study tests a new blood thinner to prevent strokes and blood clots in people with atrial fibrillation (a common heart rhythm problem). You may qualify if you have atrial fibrillation and at least one risk factor for stroke, or if you've never taken a blood thinner before.
Alexander City, AlabamaAges 18 years+ - NCT07621003Recruiting
PULSed Field Ablation for New-Onset Atrial Fibrillation
This study tests a newer ablation technique using pulsed electrical energy to treat atrial fibrillation (an irregular heartbeat). You may qualify if you were recently diagnosed with AF and haven't had ablation before.

Testing BAY 3670549 for Recent-Onset Atrial Fibrillation
This study tests a new drug called BAY 3670549 to see if it can help convert atrial fibrillation (an irregular heartbeat) back to normal rhythm. You'll receive the study drug or a placebo along with a procedure to restore your heart's normal rhythm, and researchers will monitor how well it works and how safe it is.

Common questions
- Are there clinical trials for atrial fibrillation?
- Yes. Clin2 currently lists 541 recruiting atrial fibrillation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a atrial fibrillation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a atrial fibrillation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
