- NCT05568069Recruiting
Study of defibrillator implants for non-ischemic weak heart
This study looks at whether implantable defibrillators can reduce dangerous heart rhythms in people with non-ischemic cardiomyopathy (heart weakness not caused by blocked heart arteries), a heart scar, and very low pumping strength despite best treatment. It compares different approaches to choosing which patients should receive these devices.
High Wycombe, BuckinghamshireAges 18 years+ - NCT06672159Recruiting
Double shock for out-of-hospital cardiac arrest
This trial tests a new way of giving two quick shocks to restart the heart in people who have a cardiac arrest outside the hospital. If you had a shockable heart rhythm, this approach might help improve your chances of survival.
TrondheimAges 18 years+ - NCT06739239Recruiting
French cohort study of an extra-vascular ICD
This study follows patients who receive a new type of implantable defibrillator that sits outside the heart and blood vessels. It aims to collect information about how well the device works and how safe it is over time.
ParisAges Any age - NCT07174986RecruitingPhase 2/Phase 3
Double defibrillation for out-of-hospital cardiac arrest
This trial tests whether giving two shocks in a row (instead of one) helps restart the heart in people who have a cardiac arrest outside the hospital and need a defibrillator.
AmsterdamAges 18 years+ - NCT07791407Recruiting
Heart imaging to guide defibrillator placement in heart failure
This study uses an MRI scan of the heart to better identify which people with heart failure need a defibrillator along with a special pacemaker (cardiac resynchronization therapy). The scan may help doctors decide if the device could improve your heart's pumping and reduce risks.
Madurai, Tamil NaduAges 18 years+ - NCT07649616Enrolling by invitation
Training Law Enforcement to Use Heart-Restart Devices
This study helps police officers learn to use automated external defibrillators (AEDs)—machines that can restart a stopped heart during cardiac emergencies. The goal is to increase how often these devices are used and improve survival rates when officers respond to cardiac arrest calls.
Detroit, MichiganAges 18 years+ - NCT05106062Recruiting
Remote heart monitoring program for defibrillator patients
This trial studies whether using a remote monitoring device for people with certain heart devices improves outcomes and is worth the effort/cost. It looks at results for different patient groups and needs people to actively use the monitoring system.
SeoulAges 19–80 - NCT07157449Recruiting
ECG markers for subcutaneous defibrillator eligibility
This study looks at electrocardiogram (ECG, a heart rhythm test) markers to see who might be eligible for a subcutaneous defibrillator (a device placed under the skin to prevent sudden cardiac arrest). If you are seeing a cardiologist for any reason and are over 18, you may be able to join.
Nantes, NantesAges 18 years+ - NCT03521050Recruiting
Registry study of ICD leads implanted since 2006
This study keeps a long-term record of people who get an ICD (a device that helps treat dangerous heart rhythms) and its lead. It may help doctors learn how ICD leads perform over time.
LucerneAges Any age - NCT05116176Enrolling by invitation
Study of experiences after getting an ICD for heart protection
This study follows people who are scheduled to get a new ICD (a device that helps protect the heart) and asks about their experiences and quality of life. It may help doctors understand what patients feel and how people do after ICD implantation.
Boston, MassachusettsAges 65 years+ - NCT06654284Enrolling by invitation
Quality of life after ICD implant or battery change
This study looks at how people feel and live their daily lives after getting an ICD or having the battery changed. Researchers want to understand your quality of life over time.
LeuvenAges 18 years+ - NCT07005232Enrolling by invitation
OmniaSecure defibrillation lead safety study
This study follows patients who have or will receive the OmniaSecure defibrillation lead to see how well it works and how reliable it is over time. If you have this lead, you may be able to help researchers understand its long-term performance.
Birmingham, AlabamaAges Any age - NCT03837574Recruiting
Registry for people with Tetralogy of Fallot and a defibrillator
This is a national registry that collects information about people with Tetralogy of Fallot who have an implantable defibrillator. It helps researchers better understand outcomes and care needs in this specific group.
ParisAges 18 years+ - NCT05665608Recruiting
Prevent sudden death after a heart attack with a defibrillator
This trial studies whether implanting a defibrillator (ICD) soon after a heart attack can lower the risk of sudden cardiac death in people with weaker heart pumping and symptoms of heart failure. It compares strategies around defibrillator implantation, aiming to improve safety and outcomes.
FeldkirchAges 18 years+ - NCT05769036Recruiting
Biventricular vs left bundle pacing for heart failure outcomes
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
TomskAges 18–80 - NCT06556667Recruiting
Comparing two cardioversion methods for persistent AFib
This trial compares two ways of doing cardioversion (a procedure to restore normal heart rhythm) for people with persistent atrial fibrillation. It aims to see if one approach leads to a better recovery and fewer complications.
Ottawa, OntarioAges 18 years+ - NCT06781892Recruiting
Defibrillation strategies for cardiac arrest outside the hospital
This trial tests different ways of using defibrillators to restart the heart in people who have a cardiac arrest outside a hospital. It compares two defibrillator machines used together to see if one approach works better for shockable heart rhythms.
AalborgAges 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+ - NCT02845531RecruitingPhase 4
Defibrillator device vs medicines for a rare heart spasm after arrest
This trial compares an implantable defibrillator device plus best care versus best medicines alone in people who survived a cardiac arrest caused by a specific abnormal heart rhythm. It focuses on variant angina, where a heart-spasm problem can trigger dangerous rhythm events, to see which approach prevents future events.
Bucheon-siAges 18 years+ - NCT07323667Enrolling by invitation
Study of a first responder system for cardiac arrest in Zug
This trial is studying a new system where trained volunteers respond quickly to help people whose heart stops outside of a hospital in Zug, Switzerland. The goal is to see if this system improves survival and recovery.
Zug, Canton of ZugAges 18 years+ - NCT07746336RecruitingPhase 4
Guiding heart ablation with 3D heart mapping
This trial tests a new heart-mapping technique to help doctors treat a fast heart rhythm caused by heart disease. It might improve the precision of the procedure, making it safer and more effective for patients with this condition.
BarcelonaAges 18–99 - NCT04840797Recruiting
Registry for HeartStart HS1 use during suspected cardiac arrest
This study collects real-world information about people who had a suspected cardiac arrest and where the HeartStart HS1 defibrillator was used with specific Philips pad types. It may help improve how emergency teams respond in the future.

Common questions
- Are there clinical trials for defibrillators?
- Yes. Clin2 currently lists 66 recruiting defibrillators 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 defibrillators 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 defibrillators 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.
