Recruiting studies
- 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+ - NCT06001073Recruiting
Heart and brain disease health prediction study
This study uses advanced health data to predict how heart and brain conditions may progress. It aims to help doctors provide better care for people with these diseases.
Xi'an, ShaanxiAges 3–80 - NCT06055751Recruiting
Heart rhythm monitoring after aortic valve replacement
This trial studies people who had a heart valve procedure called TAVI and later had a heart rhythm problem. You will get a tiny heart monitor placed under your skin to track your heart rhythm over time and help doctors understand how common these problems are.
Kansas City, MissouriAges 18 years+ - NCT06090591Recruiting
Heart condition research registry at Dubrava Hospital
This study is a registry that will collect information from people with certain heart conditions (like having a pacemaker, a blood clot, a heart attack, or a valve replacement procedure called TAVI). The goal is to learn more about these conditions and how they are treated.
ZagrebAges 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 - 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 - NCT06358391Recruiting
Comparing two needles for left atrial access in heart procedures
This trial compares two devices used to create a small opening in the wall between the upper chambers of the heart so doctors can reach the left side to treat heart rhythm problems or other conditions. It may help if you need a left atrial procedure and are healthy enough for the puncture.
Bucheon-siAges 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+ - NCT06455644Recruiting
CT vs. X-ray for sizing heart device in AF treatment
This study tests whether using a CT scan or a special X-ray (DSA) is better for picking the right size of a left atrial appendage closure device during a combined ablation and closure procedure. It aims to make the procedure safer and more effective.
Foshan, GuangdongAges 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+ - 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+ - 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+ - 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 - 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+ - NCT07103733Recruiting
Adding MRI and monitoring to mitral valve repair study
This study is for people already in the PRIMARY trial who are having mitral valve repair surgery. It adds an extra MRI scan and possibly a heart rhythm monitor to learn more about heart recovery after repair.
Los Angeles, CaliforniaAges 60 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 - 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+ - 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+ - NCT06100770Recruiting
Aveir leadless pacemaker study for Medicare patients
This study looks at how well a new type of pacemaker, called Aveir AR, works for people with Medicare. It helps doctors understand if this leadless pacemaker is safe and effective for treating slow heart rhythms.
Sylmar, CaliforniaAges 18 years+ - NCT06954103Recruiting
Stroke and heart health study for recent stroke patients
This study looks at how a moderate to severe stroke can affect your heart. It aims to understand the link between stroke and heart problems, which may help improve future care.
Wuhan, HubeiAges 18 years+ - NCT06607471Recruiting
Study on non-ischemic heart muscle diseases
This study looks at different types of heart muscle diseases that are not caused by blocked arteries (non-ischemic cardiomyopathies). It aims to better understand how to diagnose, predict outcomes, and treat these conditions by gathering information from many patients over time.
Milan, MilanoAges 18 years+ - NCT06964464RecruitingPhase 4
Comparing two heart failure medications in ICD patients
This trial compares two beta-blocker medications, carvedilol and metoprolol succinate, to see which one works better for people with heart failure who have an implantable cardioverter defibrillator (ICD). If you are currently taking metoprolol succinate, you may be able to switch to carvedilol and help researchers find the best treatment.
Scottsdale, ArizonaAges 18 years+ - NCT01999140Recruiting
ICD and CRT-D device registry for patients worldwide

Common questions
- Are there clinical trials for arrhythmias, cardiac?
- Yes. Clin2 currently lists 85 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?
