• HeartBeam ECG Registry: See How Heartbeat Patterns Look Across People

  This registry tests HeartBeam ECG recordings in real-world patients to build a de-identified database for research.

  Recruiting HeartBeam, Inc. · Pittsburgh, Pennsylvania · NCT07501299

• Early rhythm control treatment for subclinical atrial fibrillation

  This study tests whether starting rhythm-control treatments early can reduce abnormal heart rhythm episodes in people whose subclinical atrial fibrillation was found by implantable heart devices.

  Recruiting Samsung Medical Center · Seoul, Seoul · NCT07447297

• ICE-guided cavotricuspid isthmus ablation with a circular pulsed-field catheter

  This will see if a circular-shaped pulsed field ablation catheter, guided by intracardiac echocardiography, can safely and effectively achieve acute cavotricuspid isthmus ablation in adults with atrial fibrillation.

  Recruiting Beijing Anzhen Hospital · Beijing · NCT07353775

• Using the VERAFEYE imaging and navigation system to guide catheter ablation for atrial arrhythmias

  This study will try the VERAFEYE imaging and guidance system during catheter ablation in adults with atrial flutter or atrial fibrillation to see if it integrates well with standard procedures.

  Recruiting LUMA Vision Ltd. · Split · NCT07271238

• Anatomical navigation to guide catheter ablation for atrial fibrillation and flutter

  This trial will test whether the VERAFEYE Anatomical Guidance System helps doctors guide catheter ablation in adults with atrial fibrillation or atrial flutter.

  Recruiting at 2 sites LUMA Vision Ltd. · Split and 3 other locations · NCT07210151

• Tracking outcomes after heart rhythm procedures in Düsseldorf.

  This registry collects information to see how safe and effective routine electrophysiology procedures (like catheter ablation and cardioversion) are for people treated for AF, atrial flutter, supraventricular tachycardias, or VT at University Hospital Düsseldorf.

  Recruiting Heinrich-Heine University, Duesseldorf · Düsseldorf · NCT07196176

• Pulsed field ablation registry for atrial arrhythmias in Poland.

  This project will collect information to see how well pulsed field ablation works and how safe it is for people in Poland having ablation for atrial fibrillation, atrial flutter, or atrial tachycardia.

  Recruiting Wroclaw Medical University · Wroclaw, Lower Silesian Voivodeship · NCT07109141

• Using a quick CT scan to check for left atrial clots before cardioversion in the Emergency Department

  This will test whether a rapid cardiac CT in the ED to look for left atrial clots lets people with symptomatic atrial fibrillation or flutter have safe same‑day cardioversion instead of being admitted or delayed.

  Recruiting at 3 sites Ottawa Heart Institute Research Corporation · Hershey, Pennsylvania and 2 other locations · NCT07002450

• Monitoring heart rhythm after noncardiac surgery

  This study is testing if wearing a portable heart monitor for up to 14 days after noncardiac surgery can help find heart rhythm problems that are often missed, to improve care for patients.

  Recruiting at 2 sites Population Health Research Institute · Hamilton, Ontario and 5 other locations · NCT06519747

• Surgical procedure to prevent heart rhythm issues after cardiac surgery

  This study is testing a surgical procedure to see if it can help prevent heart rhythm problems after heart surgery for patients who haven't had these issues before.

  Recruiting at 15 sites Population Health Research Institute · Louisville, Kentucky and 18 other locations · NCT06486636

• Registry for Atrial Fibrillation Care Guidelines

  This study is tracking how well hospitals are treating patients with Atrial Fibrillation to make sure they get the best care possible.

  Recruiting American Heart Association · Dallas, Texas · NCT06245187

• Long-term outcomes for patients with cardiac arrhythmias

  This study looks at how well treatments for heart rhythm problems work over time and what factors might affect their success for patients with conditions like atrial fibrillation and ventricular tachycardia.

  Recruiting Universitätsklinikum Hamburg-Eppendorf · Hamburg · NCT05521451

• Comparing two electrode positions for heart rhythm restoration in atrial fibrillation

  This study is testing whether using two different electrode positions during heart rhythm restoration can help people with atrial fibrillation feel better and have more successful treatments.

  Recruiting at 3 sites McMaster University · Hamilton, Ontario and 3 other locations · NCT05511389

• Evaluating Atrial Fibrosis as a Predictor for Post-operative Atrial Fibrillation in Cardiac Surgery Patients

  This study is trying to see if the amount of atrial fibrosis in patients can help predict if they will have heart rhythm problems after heart surgery.

  Recruiting at 3 sites Tulane University · Covington, Louisiana and 2 other locations · NCT05014802

• Investigating excessive supraventricular activity and its link to atrial fibrillation

  This study is testing whether people with extra heartbeats detected by a monitor should get more screening to find out if they have undiagnosed atrial fibrillation or flutter.

  Recruiting Karolinska Institutet · Stockholm · NCT04593498

• Optimal antithrombotic strategy for patients with atrial fibrillation undergoing PCI

  This study is testing whether a new blood-thinning treatment for patients with atrial fibrillation undergoing heart procedures is safer and just as effective as the traditional approach that includes more medications.

  Recruiting at 18 sites Phase 4 St. Antonius Hospital · Aalst and 19 other locations · NCT04436978

• Comparing LAA closure and anticoagulation for atrial fibrillation patients after brain bleeding

  This study is testing whether closing a part of the heart or using blood thinners is better for preventing strokes in patients with atrial fibrillation who have had a brain bleed.

  Recruiting at 29 sites Jena University Hospital · Mannheim, Baden-Wurttemberg and 38 other locations · NCT04298723

• Comparing treatments for acute atrial fibrillation and flutter

  This study is testing two different ways to treat people with sudden atrial fibrillation or flutter in the emergency room to see if a less immediate approach can be done safely.

  Recruiting at 3 sites Tampere University · Jyväskylä, Central Finland and 3 other locations · NCT04267159

• Registry for Atrial Fibrillation Patients in Vienna's Emergency Department

  This study is setting up a registry to help doctors better treat older patients with atrial fibrillation who come to the emergency department in Vienna.

  Recruiting Medical University of Vienna · Vienna · NCT03272620

Where are these trials running?

In 16 countries. The most sites are in United States (5 trials), Canada (4 trials), Germany (3 trials), Poland (2 trials), Croatia (2 trials). Each study page lists its sites and which ones are recruiting.

What phases are they in?

Phase 4: 1. Trials with no phase listed are usually device, behavioural or observational studies.

How do I join one?

Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
