Recruiting studies
- NCT01524276Recruiting
Registry to track outcomes of Medtronic medical devices
This is a follow-up registry that collects information from people who have (or will receive) an eligible Medtronic device. It helps the company and doctors better understand how the device works in real-world use.
Birmingham, AlabamaAges Any age - NCT07287423Recruiting
A study of a new pacemaker system for heart rhythm problems
This trial tests a new pacemaker system for people who need a pacemaker for a slow or irregular heartbeat. It aims to see if the system is safe and works well.
PragueAges 18 years+ - NCT05694572Recruiting
Device follow-up for certain MicroPort CRM heart implants
This study checks how well specific MicroPort CRM heart devices and leads work in real life over time. If you already have one of these FDA/market-approved implants and can be followed yearly, the study helps the company monitor safety and performance.
LisbonAges 18–90 - NCT05788120Recruiting
Study heart rhythm problems in adults on VA ECMO
This study looks at how often abnormal heart rhythms happen and how serious they are in adults who are supported with VA ECMO for severe heart failure. It mainly involves using medical information, aiming to better understand complications in this critical situation.
AngersAges 18 years+ - NCT06542770Recruiting
Predicting hidden atrial fibrillation after cryptogenic stroke
This trial uses a small heart monitor to see if certain heart changes can predict hidden atrial fibrillation in people who had a stroke or mini-stroke with no clear cause. It aims to find those who might benefit from blood thinners to prevent another stroke.
BarcelonaAges 50–89 - NCT07118358Recruiting
Testing a new leadless pacemaker for slow heart rhythms
This trial studies a small, leadless pacemaker that is placed directly in the heart to treat slow heart rhythms. It's designed for people who need a pacemaker for the bottom chambers of the heart.
Burlingame, CaliforniaAges 18 years+ - NCT07775976Enrolling by invitation
Whole-heart checkup with a wearable heart monitor
This study looks at how well a wearable heart monitor and special software can check the health of your whole heart and assess your risk of future heart problems. It may help doctors create more personalized care plans.
Pasadena, CaliforniaAges 18 years+ - NCT06835491RecruitingPhase 3
Amiodarone to prevent heart rhythm problems after cardiac arrest
This trial tests whether giving the drug amiodarone early can prevent dangerous heart rhythm problems in patients who survived a cardiac arrest with a shockable rhythm. If it works, it could help more people recover.
AmiensAges 18 years+ - NCT03669809Recruiting
Study of how body timing affects metabolism
This trial looks at how “biological rhythm” (your body’s timing over the day and night) relates to metabolism, or how your body processes energy. It may help researchers understand whether timing patterns affect health and metabolic functions.
Jinan, ShandongAges 18–30 - NCT06128980RecruitingPhase 2/Phase 3
Stopping heart meds after recovery from fast heartbeat damage
This trial tests if patients whose heart function returned to normal after treating a fast heartbeat can safely stop their heart failure medications. It aims to see if treatment can be withdrawn without the heart problems coming back.
CopenhagenAges 18 years+ - NCT04578249Recruiting
Blocking blue light at night after heart surgery
This trial tests whether reducing blue light at night after certain planned heart surgeries helps protect mood, thinking, and recovery. If you have no history of major mental health problems or organ problems, you may be able to join the study.
Morgantown, West VirginiaAges 45–75 - NCT05551325Recruiting
Resetting sleep timing for ICU patients to support recovery
This study tests a “sleep chronobundle,” a set of sleep and light-timing steps, to improve daily sleep-wake timing in people in the ICU on breathing or blood-pressure support. It also checks whether the body’s sleep rhythms are more aligned during critical illness and over time.
New Haven, ConnecticutAges 18 years+ - NCT06226025RecruitingPhase 2
Melatonin for Bipolar Disorder in Night Owls
This trial tests whether giving melatonin at the right time can help people with bipolar disorder who are night owls improve their mood and sleep. You would take melatonin or a placebo each evening for a few weeks while tracking your symptoms on a phone app.
Ann Arbor, MichiganAges 18–60 - 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

Common questions
- Are there clinical trials for cardiac rhythm disorder?
- Yes. Clin2 currently lists 14 recruiting cardiac rhythm disorder 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 cardiac rhythm disorder 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 cardiac rhythm disorder 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.
