Recruiting studies
- NCT05411614Recruiting
Testing two heart procedures for atrial fibrillation in heart failure
This study compares two different ablation procedures (treatments that target heart rhythm triggers) for people with atrial fibrillation and reduced heart pumping. It aims to see which approach works best and is safest for improving your heart rhythm when you also have heart failure.
ChertseyAges 18 years+ - NCT05594368RecruitingPhase 1
Test targeted radiation to treat recurrent ventricular tachycardia
This trial studies a radiation approach (called stereotactic body radiation therapy, or SBRT) to treat ventricular tachycardia (a dangerous heart rhythm) that keeps coming back. It aims to reduce the rhythm episodes in people who have already tried catheter ablation (a procedure to cauterize rhythm sources) or cannot have it.
OstravaAges 18 years+ - 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+ - NCT05452356Recruiting
Testing a phone-based care plan for people with heart conditions
This trial tests a phone app that helps deliver organized “care plans” for people with cardiovascular (heart/vessel) conditions. You might join to see if this phone-based support improves how care is delivered and helps you manage your condition.
London, OntarioAges 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+ - NCT05122962Recruiting
MRI study of heart rhythm and exercise capacity after congenital surgery
This study looks at how blood flow and heart rhythm may affect exercise ability in people born with certain heart defects that have been repaired or treated. It uses a specialized heart MRI and ultrasound measurements to better understand these problems and their causes.
Rochester, MinnesotaAges 18 years+ - NCT05073419Recruiting
Test for heart rhythm issues after a heart attack
This trial checks how well a small heart monitor device can detect abnormal heart rhythms after a recent heart attack. It may help doctors catch rhythm problems early, which could improve follow-up care after discharge.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05034432RecruitingPhase 4
Test treatment for dangerous heart rhythm episodes in LVAD patients
This trial studies a procedure to fix abnormal heart rhythms (ventricular tachycardia or ventricular fibrillation) in people who have an LVAD and a defibrillator (ICD) or an alternative device. It may help prevent future dangerous rhythm episodes after LVAD treatment.
Phoenix, ArizonaAges 18 years+ - NCT05014802Recruiting
MRI scans before heart surgery to predict post-surgery atrial fibrillation
This study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
Covington, LouisianaAges 40–120 - NCT04685317Recruiting
Sentinel brain-protection device during atrial fibrillation ablation
This trial tests whether a specialized “brain protection” device can improve safety during atrial fibrillation (AF) catheter ablation. It may help reduce the risk of stroke or related complications while treating AF.
Rochester, MinnesotaAges 18 years+ - NCT04520347Enrolling by invitation
Registry for heart rhythm ablation in VT or PVC
This study is a “registry,” meaning it collects information about people undergoing a procedure to treat abnormal heart rhythms like ventricular tachycardia (VT) or premature ventricular contractions (PVCs). It may help researchers better understand which patients benefit from the procedure and how it is done over time.
Phoenix, ArizonaAges Any age - NCT00733590Recruiting
Study after ICD generator replacement for heart attack patients
This study follows people who had a prior heart attack and later received a replacement ICD (a device that helps prevent sudden dangerous heart rhythms). It is observational, meaning it mainly looks at outcomes and device-related information rather than testing a new drug.
Washington D.C., District of ColumbiaAges 18–85 - NCT03775954Recruiting
Fetal heart testing in high-risk pregnancies after baby loss
This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.
Madison, WisconsinAges 18 years+ - NCT03209583Recruiting
Test of fast-pacing therapy for congenital heart rhythm issues
This trial studies whether a device-based fast pacing therapy (called ATP) can better treat certain rapid heart rhythm problems in people born with a heart condition. It may help prevent or reduce episodes of atrial (upper-chamber) arrhythmias that occur despite having a pacing/defibrillator device.
Los Angeles, CaliforniaAges Any age - NCT03049254Recruiting
Registry and blood/tissue study for certain sudden heart death causes
This study builds a registry and collection of samples to better understand families affected by sudden heart death and related heart rhythm problems that are not clearly caused by a heart attack. It may help researchers identify patterns and improve future care, and it offers a way for patients and families to contribute to research.
Rochester, MinnesotaAges Any age - 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 - NCT02413450Enrolling by invitation
Using patient DNA cells to study inherited heart rhythm risks
This study uses your blood or genetic information to make “iPS cells,” lab-grown cells that can help researchers study inherited heart rhythm problems like LQTS, Brugada syndrome, CPVT, or early repolarization syndrome. It may help improve understanding of why these rhythms happen and guide future treatments.
Baltimore, MarylandAges 18–85 - NCT00271180Recruiting
Tracks long-term performance of Medtronic heart devices
This study follows how well certain Medtronic heart devices work over the long term. You may be included if you have a qualifying Medtronic implant and the research team can reliably get your implant and follow-up information.

Common questions
- Are there clinical trials for arrhythmia?
- Yes. Clin2 currently lists 163 recruiting arrhythmia 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 arrhythmia 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 arrhythmia 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.
