Recruiting studies
- NCT07276139Recruiting
Heart device experience and outcomes study
This study collects information from people who have a heart device (like a pacemaker) to learn how these devices work in real life and how they affect patients. By joining, you help doctors improve care for future patients.
Canberra, Australian Capital TerritoryAges 18 years+ - NCT05521451Recruiting
Study for adults with heart rhythm problems
This trial is a “clinical cohort” study, meaning it follows adults with certain heart rhythm issues to understand them better. Your participation may help researchers learn what to expect and how best to support people over time.
HamburgAges 18 years+ - NCT06272396Recruiting
Testing a smartwatch to record heart rhythms
This study is testing whether a connected watch (like a smartwatch) can accurately record your heart's electrical activity (an ECG) during a hospital stay or clinic visit. If it works well, it could make checking your heart easier and more convenient.
PessacAges Any age - NCT06906432Recruiting
Brain-Heart Injury After Brain Bleed Study
This study looks at how a brain bleed can affect the heart. Researchers hope to understand the link between brain and heart injury to help improve care for people who have had a brain bleed.
Beijing, Beijing MunicipalityAges 18–80 - NCT05890664RecruitingPhase 3
Colchicine after shock treatment to stop atrial fibrillation
This trial tests whether colchicine given after cardioversion (a procedure that restores normal rhythm) helps keep the heart in normal rhythm afterward. It may help some people have fewer early returns of atrial fibrillation.
Bruderholz, Basel-LandschaftAges 18 years+ - NCT06938412Recruiting
Exercise and Fitbit for Afib patients
This study tests whether using a Fitbit activity tracker and a supportive exercise program helps people with AFib become more active. It may help you feel better and manage your heart rhythm.
New York, New YorkAges 18 years+ - NCT06870175Recruiting
Smart shirt heart monitoring trial
This trial tests a smart textile ECG monitor worn as a shirt to track your heart rhythm for up to 14 days. It may replace the usual sticky electrodes and wires, making monitoring more comfortable.
Newmarket, OntarioAges 18 years+ - NCT06772493Recruiting
First test of a new ICE ultrasound tool in people
This study is testing a new type of ICE ultrasound tool during heart procedures. The goal is to see how well it works in real people.
Jonesboro, ArkansasAges 18 years+ - NCT05829993Recruiting
AI program to spot ECG heart rhythm risk
This study tests an artificial intelligence (computer) tool that looks at your ECG (heart tracing) to help detect abnormal heart electrical patterns and the risk of dangerous rhythm problems. You may be helping clinicians screen for rhythm risk using ECG data.
ParisAges 18 years+ - NCT06668831Recruiting
FGF23 and heart rhythm in dialysis patients
This study looks at whether a blood protein called FGF23 is linked to irregular heartbeats in people on long-term hemodialysis (kidney dialysis). It may help doctors better predict heart risks.
LuganoAges 18 years+ - NCT06577714Enrolling by invitation
Heart ablation guided by advanced imaging
This study tests a new imaging technique to help guide heart ablation procedures for certain heart rhythm problems. It may help doctors see exactly where to treat.
New York, New YorkAges 18 years+ - NCT06360939Recruiting
Radiation or ablation for ventricular tachycardia in heart disease
This trial compares two treatments—radiation therapy or catheter ablation—for people with structural heart disease who have a type of fast heart rhythm called ventricular tachycardia. It aims to see which approach works better to prevent repeat episodes.
WestmeadAges 18 years+ - NCT06096246Recruiting
Comparing treatments for persistent atrial fibrillation
This study compares two treatments for persistent atrial fibrillation (AF) that lasts more than 7 days but less than 2 years: electrical cardioversion (a shock to reset your heart rhythm) versus catheter ablation (using radio waves to fix the heart's electrical pathways). It aims to find which option works better for patients like you.
LondonAges 18–85 - NCT05371405Recruiting
Using computer learning to improve care for atrial fibrillation patients
This study uses machine learning (computer pattern-finding) to better understand atrial fibrillation and guide care around the time of an ablation procedure. It may help refine how doctors treat certain AF patients based on their heart patterns.
Stanford, CaliforniaAges 22–80 - NCT05560958Recruiting
Heart procedure study for specific BIOTRONIK EP products
This study collects real-world follow-up information after certain heart procedures that use specific BIOTRONIK equipment. It may help confirm how well these devices work in everyday care and improve future recommendations.
Bernau bei Berlin, BrandenburgAges 18 years+ - NCT05366361Recruiting
Study of persistent atrial fibrillation during heart procedures
This study looks at what happens in the heart in people with persistent atrial fibrillation when they undergo an ablation or Maze surgery. It may help doctors better understand the condition and improve future care for people needing these procedures.
Stanford, CaliforniaAges 22–80 - NCT05184790Recruiting
Using imaging during radiation therapy to improve AI planning
This study tests how well an artificial intelligence system can use special X-ray images taken during certain radiation treatments to improve care. You may qualify if you’re having radiation for specific conditions and your treatment center uses the required imaging steps.
Saint Leonards, New South WalesAges 18 years+ - NCT02725060Enrolling by invitation
Study of autoimmune changes in postural tachycardia syndrome
This trial studies whether an autoimmune (immune system–related) process is involved in postural tachycardia syndrome (POTS), a condition where your heart rate rises when you stand. The study may help researchers understand what causes POTS and how it could be treated or monitored.
Oklahoma City, OklahomaAges 18–50 - NCT05439031RecruitingPhase 2
Stereotactic radiation to reduce recurrent dangerous heart rhythm episodes
This Phase 2 study tests a precise form of radiation therapy to control recurrent ventricular tachycardia (VT), a dangerous fast heart rhythm. It may help people whose VT keeps coming back despite heart medicines and/or ablation, especially when ablation is not possible.
Amsterdam, North HollandAges 18 years+ - NCT05631730RecruitingPhase 3
Flecainide plus metoprolol vs metoprolol alone for rhythm control
This trial studies whether adding flecainide to metoprolol can better reduce dangerous heart rhythm problems in people with mitral valve prolapse. It also checks safety and side effects compared with metoprolol alone.
OsloAges 18 years+ - NCT07830888Recruiting
Mitral valve prolapse rhythm risk study
This study looks at people with mitral valve prolapse who also have rhythm problems like extra beats or fast heart rhythms. The goal is to better understand risk and improve care.
OsloAges Any age - NCT06100770Recruiting

Common questions
- Are there clinical trials for arrhythmias, cardiac?
- Yes. Clin2 currently lists 89 recruiting arrhythmias, cardiac 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 arrhythmias, cardiac 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 arrhythmias, cardiac 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.
