Recruiting studies
- NCT06055504Recruiting
Personalized defibrillator plan for non-ischemic heart failure (SPANISH-1)
This trial is testing a personalized approach to deciding who gets an implantable defibrillator (ICD) for people with heart failure due to dilated cardiomyopathy (not from blocked arteries). It aims to see if MRI scans and other factors can better match the device to those who need it most.
Santiago de Compostela, A CoruñaAges 18 years+ - NCT06324682Recruiting
Comparing heart pacemaker types for better treatment
This trial looks at different ways to pace the heart (like left, right, or both sides) to see which works best for people who need a pacemaker. If you have a heart condition requiring a pacemaker, this study may help find the safest and most effective option for you.
Ferrara, FEAges 18 years+ - NCT03847025Recruiting
Lead extraction registry for pacemaker and defibrillator patients
This registry collects information from people who are having pacemaker or defibrillator leads removed. It helps doctors and researchers understand how these procedures are done and what happens afterward.
Portland, OregonAges Any age - 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 - NCT03588286Recruiting
Check heart rhythm risk early after a heart attack
This trial tests whether a programmed heart rhythm test can better identify who needs an implanted defibrillator (ICD) soon after a heart attack. It may help prevent dangerous fast heart rhythms (tachyarrhythmias) by guiding who gets an ICD.
Boston, MassachusettsAges 18–85 - 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+ - NCT07849764Recruiting
Subcutaneous ICD suitability over time in arrhythmogenic cardiomyopathy
This study looks at whether a special type of defibrillator that sits under the skin is a good option for people with arrhythmogenic cardiomyopathy, a heart condition that can cause dangerous heart rhythms. It aims to help doctors decide who might benefit from this device and when.
São Paulo, São PauloAges 18 years+ - NCT05835791Recruiting
Study of new ventricular arrhythmia patients getting ICD follow-up
This study looks at people who are newly diagnosed with a dangerous heart rhythm called ventricular tachycardia (VT) and who are getting an implantable cardioverter-defibrillator (ICD). It may help improve how patients are followed in the ICD clinic after the initial hospitalization.
Vancouver, British ColumbiaAges 18 years+ - NCT06597578Recruiting
Registry for pacemaker and ICD lead removal
This trial is a registry that collects information from people who need to have a pacemaker or ICD lead removed. It helps doctors learn more about the procedure and how to improve care.
CologneAges 18 years+ - NCT06607471Recruiting
Study on non-ischemic heart muscle diseases
This study looks at different types of heart muscle diseases that are not caused by blocked arteries (non-ischemic cardiomyopathies). It aims to better understand how to diagnose, predict outcomes, and treat these conditions by gathering information from many patients over time.
Milan, MilanoAges 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 - NCT06388382Recruiting
Testing the beep of a special defibrillator
This study looks at the beeping sound (alert tone) from a certain type of defibrillator placed under the skin. The goal is to understand if patients can hear and recognize these sounds, which could be important for safety.
CologneAges 15–100 - NCT05760924Recruiting
Testing a new heart pacing method for CRT nonresponders
This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
TomskAges 18–80 - NCT05971225Recruiting
Testing remote heart monitoring to improve heart outcomes
This study checks whether starting remote wireless heart monitoring for people with heart failure helps improve important heart outcomes. It may help your care team catch warning signs earlier by receiving your heart data from home.
Suwon, Kyonggi DoAges 20 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+ - NCT06756282Recruiting
Pacemaker use one year after TAVR
This study looks at people who need a permanent pacemaker after having a TAVR procedure (a type of heart valve replacement). It aims to see how many people still need the pacemaker one year later.
MontpellierAges Any age - NCT04576130Recruiting
ICD study after cardiac arrest from an abnormal heart rhythm
This study looks at an implantable defibrillator (ICD) strategy in people who survived a cardiac arrest caused by an abnormal rhythm (ventricular fibrillation or ventricular tachycardia). It aims to reduce the risk of another dangerous rhythm after the blocked heart arteries are fully treated.
CopenhagenAges 18 years+ - NCT07430813Recruiting
Drone delivery of defibrillators for bystanders
This study tests if drones can deliver a defibrillator to people who witness a cardiac arrest, helping them provide lifesaving care before an ambulance arrives. You may be asked to use a training manikin to see how quickly you can help.
Guildford, SurreyAges 18 years+ - NCT06707662Recruiting
Pacing methods to protect heart function
This trial tests two pacing approaches to see which one better prevents weakening of the heart's main pumping chamber. It's for people who need a pacemaker for a slow heart rhythm and are expected to rely on it heavily.
BarcelonaAges 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.
AdelaideAges 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 - NCT07354347Recruiting
Finding the best pace settings for ICDs
This trial studies how to set the pacemaker function in an implantable cardioverter-defibrillator (ICD) to stop dangerous heart rhythms more effectively. It may help you if you have an ICD for preventing or treating fast heartbeats.

Common questions
- Are there clinical trials for defibrillators?
- Yes. Clin2 currently lists 65 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.
