Stopping blood thinners after successful AF ablation with close heart monitoring
This trial tests whether people with atrial fibrillation who have had a successful ablation procedure can safely stop taking blood thinners (NOACs) if they wear a monitor to check for any silent heart rhythm problems. It may help you avoid the risks of long-term blood thinner use if your ablation has been effective.
Hefei, AnhuiAges 18–80 - NCT07002450Recruiting
CT scan to check for clots before heart shock therapy
This trial uses a CT scan of the left atrium to check for blood clots before a procedure called cardioversion (an electric shock to restore normal heart rhythm). The goal is to see if the CT scan can safely replace other imaging methods in the emergency department, helping to speed up treatment.
Hershey, PennsylvaniaAges 18 years+ - NCT07109141Recruiting
Registry of Heart Rhythm Fix Procedures Using Pulsed Field Ablation in Poland
This study tracks people who have a procedure called pulsed field ablation to fix an abnormal heart rhythm (atrial arrhythmia). It's a registry, meaning researchers will collect information to learn more about how well the treatment works and how safe it is.

Comparing energy types for repeat atrial fibrillation treatment
This trial compares two different energy methods (electroporation vs radiofrequency ablation) guided by 3D imaging for people who have had a prior ablation for atrial fibrillation but still have recurrences. It aims to find which method is safer and more effective for repeat procedures.
WroclawAges 18–85 - NCT07171463Recruiting
New ablation for paroxysmal atrial fibrillation
This trial tests a new treatment that uses two types of energy (pulsed field and radiofrequency) to fix the heart's electrical signals in people with paroxysmal atrial fibrillation (AFib that comes and goes). It aims to be more effective and safer than standard ablation alone.
Rzeszów, Podkarpackie VoivodeshipAges 18 years+ - NCT07196176Recruiting
Heart rhythm test registry at University Hospital Düsseldorf
This registry collects information from people who have had or are scheduled to have a heart rhythm test or a procedure to restore a normal heartbeat at University Hospital Düsseldorf. It helps doctors understand more about heart rhythm problems and treatments over time.
DüsseldorfAges 18 years+ - NCT07271238Recruiting
Study of a new imaging system for heart ablation
This study tests a new imaging system (VERAFEYE) that helps doctors guide catheter ablation, a procedure to fix irregular heartbeats like atrial fibrillation. It aims to see if the system makes the procedure safer or more effective.
SplitAges 18 years+ - NCT07353775Recruiting
Heart procedure using imaging and pulsed energy
This trial uses a special imaging tool inside the heart to guide a new type of energy (pulsed field) to treat a specific area in the heart that can cause atrial fibrillation (an irregular heartbeat). It may help people with paroxysmal or persistent atrial fibrillation who need a procedure called CTI ablation.
BeijingAges 18 years+ - NCT02347111RecruitingPhase 4
Genetic study to guide antiarrhythmic drugs for atrial fibrillation
This study looks at how a person’s genetics may affect how well and safely antiarrhythmic medicines work for atrial fibrillation (AF). If you join, you may get medicine options like flecainide or sotalol, and researchers compare outcomes to genetic information.
Chicago, IllinoisAges 18–100 - NCT03272620Recruiting
Emergency atrial fibrillation patients invited to study
This study includes people who have atrial fibrillation and are seen in the emergency department. It aims to learn from emergency care and may help improve how atrial fibrillation is managed in the ER.
ViennaAges 18 years+ - NCT03355456Recruiting
Catheter ablation for atrial fibrillation with low-voltage mapping
This trial studies a catheter procedure that targets areas in the heart that show low electrical voltage to treat atrial fibrillation (an irregular heartbeat). You may be eligible if you have non-paroxysmal atrial fibrillation, have tried heart rhythm medicines, and your scan shows low-voltage areas in the left atrium.
Cleveland, OhioAges 18–85 - NCT07407790Recruiting
Smartphone heart check after stroke
This study tests whether using a smartphone app to check your heart rhythm after a stroke can find hidden atrial fibrillation (an irregular heartbeat). If you had a recent stroke or TIA and are not already on blood thinners, you may be able to help doctors detect and prevent future strokes.
KristiansandAges 18 years+ - NCT07447297Recruiting
Early Rhythm Control for Device-Detected Fast Heart Episodes
This trial tests whether starting treatment early to control your heart's rhythm can help people with a heart device who have short bursts of a fast heartbeat (called atrial high rate episodes) but haven't yet been diagnosed with atrial fibrillation on a standard EKG or Holter monitor.
Seoul, SeoulAges 19 years+ - NCT06989775Recruiting
BoxX-NoAF Trial: Preventing Stroke During Heart Surgery
This trial tests a device to close a small pouch in the heart during planned bypass surgery, to help prevent future strokes. It is for people who have never had an irregular heartbeat and are at higher stroke risk due to age and other factors.
Jonesboro, ArkansasAges 65 years+ - NCT07563257Recruiting
Comparing Two Mapping Catheters for Heart Rhythm Ablation
This trial compares two types of specialized catheters used during heart rhythm ablation procedures to help doctors confirm they've created the right burn patterns. If you're having ablation for persistent atrial fibrillation or flutter with complex burn lines planned, this trial may help improve how your procedure is done.

Pulsed-field ablation for recurrent atypical atrial flutter
This study tests a new type of energy called pulsed-field ablation (PFA) to treat a specific kind of irregular heartbeat called atypical atrial flutter that keeps coming back after a prior ablation. It aims to see if this approach can safely stop the abnormal rhythm.

Common questions
- Are there clinical trials for atrial fibrillation and flutter?
- Yes. Clin2 currently lists 93 recruiting atrial fibrillation and flutter 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 and flutter 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 and flutter 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.
