Comparing two guidance methods for pulsed field ablation in atrial fibrillation
This trial compares two ways of guiding a procedure to treat atrial fibrillation (an irregular heartbeat). One uses special sound waves to see inside the heart, and the other uses electrical mapping. Both are used with the FARAPULSE system to deliver a type of energy called pulsed fields to fixed areas of the heart.

Apixaban safety and adherence for atrial fibrillation patients
This trial tests how well patients with atrial fibrillation take their apixaban medication and whether it is safe. It aims to see if using apixaban for the first time works well without causing bleeding problems.
SarajevoAges 18 years+ - NCT06724718Recruiting
Using a smartwatch to detect atrial fibrillation after chest surgery
This trial tests whether a smartwatch can detect atrial fibrillation in people who have had major chest surgery (like lung removal) within the last 48 hours. If successful, this could help catch heart rhythm problems early without extra hospital equipment.
AmiensAges 18 years+ - NCT03091452Recruiting
Atrial fibrillation surgery registry for people treated with ablation
This study is a real-world registry that collects health information from people who have atrial fibrillation and were treated with a heart surgery procedure called ablation. It may help doctors better understand outcomes and care for people with this condition.
München, BavariaAges 18–100 - NCT04281329Recruiting
CT and heart MRI add-on for atrial fibrillation ablation
This trial studies whether CT scans and heart MRI scans (done around the time of atrial fibrillation ablation) can help care planning and results. It may help your team better understand your heart before and after the procedure.
ParisAges 18 years+ - NCT04606693Recruiting
Screening for sleep apnea before heart rhythm ablation
This study looks at whether checking for sleep apnea (breathing pauses during sleep) and treating it helps people prepare for atrial fibrillation ablation. It may help by improving outcomes for patients with atrial fibrillation who keep having episodes despite medication.
Madrid, MadridAges 18 years+ - NCT05427435Recruiting
Testing alcohol treatment of a heart vein during atrial fibrillation ablation
This study tests whether applying a small amount of alcohol to a specific heart vein (“vein of Marshall”) is safe and feasible during a standard atrial fibrillation (AF) ablation. It may help improve AF treatment, but the goal here is mainly to see if the approach can be done safely in the right patients.
PessacAges 18 years+ - NCT05598632Recruiting
People with atrial fibrillation registry to study stroke risk
This registry study follows people with atrial fibrillation to learn which risk factors are linked to stroke or blood clots traveling through the body. Your information helps improve how doctors predict risk and choose prevention strategies.
Beijing, Beijing MunicipalityAges 18–120 - NCT05928728RecruitingPhase 3
Colchicine for people with certain irregular heartbeats
This trial tests whether colchicine can help people with paroxysmal or persistent atrial fibrillation (AF), a type of irregular heartbeat, after a successful cardioversion. It may help reduce future AF problems, depending on the results.
HellerupAges 18 years+ - NCT05996159Recruiting
Using very high power for short duration to treat atrial fibrillation
This study tests a new way to perform a common procedure (pulmonary vein isolation) for people with paroxysmal atrial fibrillation. Instead of using the standard amount of energy for a longer time, this method uses a very high amount of energy for a very short time. This might make the procedure faster and just as safe.
SeoulAges 19 years+ - NCT06184633RecruitingPhase 4
Weight control in atrial fibrillation study
This study tests if a weight management program helps people with a new type of irregular heartbeat (atrial fibrillation) and obesity. It aims to see if losing weight can improve heart rhythm and reduce the need for further treatment.
Arnhem, GelderlandAges 18 years+ - NCT06324201Recruiting
Long-term safety of a new ablation system for paroxysmal AF
This study tests a new system (QDOT MICRO and VISITAG SURPOINT) used during a catheter ablation procedure to treat atrial fibrillation (AF). It aims to see how safe and effective it is over the long term for people whose AF comes and goes and hasn't been controlled by medication.
Birmingham, AlabamaAges 18 years+ - NCT06455098Recruiting
Pulsed field ablation for paroxysmal atrial fibrillation
This study tests a new procedure called pulsed field ablation using a special catheter to treat paroxysmal atrial fibrillation (AF), a type of heart rhythm problem that comes and goes. It may be an option for people whose AF hasn't been controlled well with medication.
Phoenix, ArizonaAges 18–80 - NCT04088071Recruiting
Ablation for heart rhythm problems using a specific technology
This study looks at how well catheter ablation works for treating certain heart rhythm disorders (like atrial fibrillation or ventricular arrhythmias) using a specific brand of catheters. The aim is to gather real-world data to better understand the procedure's outcomes.
Birmingham, AlabamaAges 18 years+ - NCT06510556Recruiting
Testing a new mapping and ablation system for AFib
This study tests a new device (FARAFLEX) that uses pulsed field energy to treat atrial fibrillation (AFib). You may qualify if you have persistent or paroxysmal AFib symptoms and have not had a prior ablation.
BrusselsAges 18 years+ - NCT06832033Recruiting
Exercise program after atrial fibrillation ablation
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.
Zaragoza, ZaragozaAges 18 years+ - NCT06883864Recruiting
Ablation for leaky valve with constant atrial fibrillation
This study tests whether a catheter ablation procedure (a way to fix abnormal heart rhythms) can help people who have both constant atrial fibrillation and severe mitral regurgitation (a leaky heart valve). It is for people whose heart valve leak is caused by the rhythm problem, not by valve damage.
Hefei, AnhuiAges 18–80 - NCT06987825Recruiting
Chinese atrial fibrillation registry study
This study tracks patients with atrial fibrillation (AF) over time to better understand the condition and improve care. You may be asked to share health information and attend follow-up visits.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06995391Recruiting
Alcohol reduction app for atrial fibrillation
This trial tests if a smartphone app can help people with atrial fibrillation reduce or stop drinking alcohol. The goal is to see if cutting down on alcohol makes AF symptoms less severe or occur less often.
San Francisco, CaliforniaAges 21 years+ - NCT07047235Recruiting
Targeted ablation for persistent atrial fibrillation

Pulsed field vs. cryoballoon ablation for persistent atrial fibrillation
This trial compares two techniques—pulsed field ablation and cryoballoon ablation—to treat persistent atrial fibrillation (a type of irregular heartbeat that lasts less than a year). The goal is to see which method works better and is safer for patients.
Sagamihara, KanagawaAges 18–85 - NCT07122336Recruiting
A better way to treat persistent atrial fibrillation
This trial tests a new method to treat persistent atrial fibrillation (a long-lasting irregular heartbeat) to see if it helps patients who haven't been helped by medication. It focuses on cleaning up the back wall of the heart to restore a normal rhythm.
ShanghaiAges 18–80 - NCT07130773Recruiting
Comparing two catheter types for atrial fibrillation ablation
This trial compares two types of special catheters (thin tubes) used during a procedure called ablation to treat atrial fibrillation (irregular heartbeat). It aims to see which catheter works better during the procedure, and may help improve future treatments for people with heart rhythm problems.

Common questions
- Are there clinical trials for atrial fibrillation?
- Yes. Clin2 currently lists 546 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.
