Recruiting studies
- 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.
Birmingham, AlabamaAges Any age - 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
This trial is a real-world registry that collects information from people who receive an implantable heart defibrillator or related device. It helps doctors understand how these devices are used and how patients do over time.
Washington D.C., District of ColumbiaAges Any age - NCT04407780Recruiting
Cardio-oncology patient registry
This is a registry (a research database) for people who are being followed in cardio-oncology, which means care for heart problems related to cancer or cancer treatments. It may help doctors better understand these conditions and improve future care.
ParisAges 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 - NCT06591260Recruiting
Heart biopsy and treatment for kids with heart inflammation
This study looks at using heart biopsies to find the cause of heart inflammation (myocarditis) in children and then tailoring treatment to that cause. It aims to improve care for children with or without irregular heartbeats.
Milan, MilanoAges birth–17 years - NCT04521790Recruiting
Biopsy-guided treatment for suspected inflammation of the heart
This study looks at people 18 and older with suspected myocarditis (inflammation of the heart). It uses an inner-heart biopsy and tailored treatment based on the likely cause to improve diagnosis and care, especially for people with different heart rhythm or non-rhythm symptoms.
Milan, MilanoAges 18 years+ - NCT06089902Recruiting
European registry for anomalous aortic origin of coronary arteries
This is a European registry for people with an anomalous origin of a coronary artery from the aorta (AAOCA). It will track how the condition is treated—whether with surgery or monitoring—to learn what works best.
Padova, PDAges Any age - NCT06511505Recruiting
Testing AI to find hidden heart conditions from ECGs
This study uses an AI tool to look at your ECG (a simple heart test) to help find early signs of atrial fibrillation (an irregular heartbeat) or structural heart disease (changes in heart structure). It aims to see if the AI can help doctors catch these conditions sooner, even in people who don't yet have symptoms.
Chicago, IllinoisAges 40 years+ - NCT07174206Recruiting
Smartwatch monitoring for heart patients
This trial tests a smartwatch tool to track heart rhythm and detect problems in people with heart disease. It may help find irregular heartbeats early during routine checkups.
São Paulo, São PauloAges 22 years+ - NCT07374263Recruiting
Do heart rhythm drugs pose risks in hospital?
This study looks at whether certain medications that can affect heart rhythm (QT-prolonging drugs) are linked to serious heart problems in adults who were hospitalized. It includes patients admitted to St. Joseph's Healthcare Hamilton or other GEMINI hospitals between 2017 and 2025.
Hamilton, OntarioAges 18 years+ - NCT05094843Recruiting
Mini-invasive surgery for lung cancer and heart rhythm changes
This study looks at how lung cancer surgery affects the heart’s electrical signals and stress response, using heart tracing tests (ECG) around the time of surgery. It may help doctors better understand and monitor heart risks in people having curative, minimally invasive lung cancer surgery.
Tampere, PirkanmaaAges 18 years+ - NCT07669493Recruiting
Heart safety during chest radiation for cancer patients
This study looks at how chest radiation affects heart function and the immune system, and whether it is safe in people with lung, esophageal, breast, or thymus cancer who have not had chest radiation before.
Shijiazhuang, HebeiAges 18 years+ - NCT07096973Recruiting
Heart rehab recovery study in Davos
This study looks at how people recover during heart rehabilitation at a clinic in Davos. By tracking your progress, researchers hope to learn what helps people get better.
Davos, Kanton GraubündenAges 18 years+ - NCT07617376RecruitingPhase 4
Flu shot before leaving hospital after heart problems
This study tests whether giving a flu vaccine to patients before they leave the hospital after a heart condition improves their health. The vaccine may help protect your heart and prevent serious flu complications while you recover.
WroclawAges 18 years+ - 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.

Common questions
- Are there clinical trials for arrhythmias, cardiac?
- Yes. Clin2 currently lists 88 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.
