ICD placement to prevent sudden heart death in people over 70
This study looks at placing an ICD, a device that can stop dangerous heart rhythms, to help prevent sudden cardiac death. It is for people over 70 with specific heart function and heart failure symptoms.
Aix-en-ProvenceAges 70 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+ - NCT06330675Recruiting
Early mobilization after pacemaker or ICD implant
This trial is testing whether getting up and moving earlier after a pacemaker or defibrillator implant is safe and helpful. If you are getting a new device for the first time, you may be able to join.
LuganoAges 18 years+ - 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+ - NCT04558723Recruiting
MRI-guided heart defibrillator placement for non-ischemic weakened hearts
This study looks at whether using a heart MRI (CMR) to guide where to place an implanted defibrillator (ICD) improves outcomes for people with a weakened heart muscle caused by non-ischemic dilated cardiomyopathy. It’s for adults who have low pumping strength and evidence of heart scarring on MRI.
Lübeck, Schleswig-HolsteinAges 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+ - NCT06842940Recruiting
Predicting best lead placement during pacemaker or ICD surgery
This study tests whether a measurement called 'slew rate' can help doctors find the best spot to attach the leads (wires) from a pacemaker or ICD to your heart. It may lead to more stable and effective placement during your procedure.
FidenzaAges 18–100 - NCT05754138Recruiting
Testing sports safety with a subcutaneous defibrillator
This study looks at whether it is safe to play sports if you have a specific type of implanted defibrillator under the skin. It will track your device performance and exercise habits, using home monitoring, to understand any risks from sports.
Tel AvivAges 10–60 - 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 - NCT06937658Recruiting
Better remote care for heart device patients
This study tests a new alert system for people with pacemakers or defibrillators that can send information directly to your care team. The goal is to improve how quickly problems are found and treated.
Boston, MassachusettsAges 18 years+ - NCT07592494Recruiting
Arm Exercise Training for Heart Failure With Device
This study compares different types of arm exercises for people with heart failure who have a pacemaker or defibrillator implanted. The goal is to see which exercise approach best improves how well your arms function and help you stay active.
ÇorumAges 18 years+ - NCT07253909Enrolling by invitation
Arm function in heart failure with ICD or CRT devices
This study looks at how well people with heart failure and certain heart devices (ICD or CRT) can use their arms and hands. It aims to understand if these devices affect upper body function.

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+ - NCT07393009Recruiting
Study of a new left bundle branch area pacing system
This study tests a new type of pacemaker system that delivers pacing to the left side of the heart through a lead placed deep in the wall between the lower chambers. The goal is to see if this approach works well for people who need a pacemaker or CRT.

- Are there clinical trials for defibrillators, implantable?
- Yes. Clin2 currently lists 42 recruiting defibrillators, implantable 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, implantable 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, implantable 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.
