- NCT04139616Recruiting
Testing a planned heart rhythm plan after aortic valve replacement
This study tests an algorithm—a step-by-step plan—for how doctors manage abnormal heart rhythms after transcatheter aortic valve replacement (TAVR). It may help guide safer, more consistent care in the weeks after the procedure.
Québec, QuebecAges 18 years+ - NCT04201015RecruitingPhase 2/Phase 3
Testing exercise pacing to improve heart pumping
This trial tests whether “pacing” your exercise (doing it at the right rate) can improve how strongly your heart pumps. It’s for people with heart failure who have a pacemaker and can safely do an exercise test.
LeedsAges 18 years+ - NCT04416958Recruiting
Pacemaker or defibrillator pacing strategy to reduce heart timing issues
This study looks at a pacing approach for people with a pacemaker or ICD (defibrillator) to help prevent the heartbeats from becoming out of sync. It may be useful if your implant team is trying to reduce pacing-related “timing” problems in the heart.
Fürth, BavariaAges 18 years+ - NCT05015660Recruiting
Testing left bundle pacing versus usual right pacing
This study compares a newer heart pacing method (left bundle branch pacing) to the standard method (right ventricular pacing) in people who need most of their heartbeats paced. It may help improve how well the heart pumps over time.
Montreal, QuebecAges 18 years+ - NCT05029570Recruiting
Heart rate control for permanent atrial fibrillation and heart failure
This trial studies whether a strategy to regularize (control) heart rate can improve outcomes in people who have permanent atrial fibrillation and heart failure. It focuses on people with recent heart-failure hospitalization and checks several heart, kidney, and health-condition limits to keep the study safe.
Madrid, MadridAges 18 years+ - NCT05127720Recruiting
Pacemaker monitoring to study sleep apnea long term
This study uses a pacemaker to track information over time related to sleep apnea. It also includes CT scans to help the researchers better understand what’s happening in and around the heart during sleep.
Innsbruck, TyrolAges 18 years+ - NCT05868616Recruiting
Checking heart resynchronization timing with a noninvasive test
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
OsloAges 18–80 - NCT06152406Recruiting
Ablate and Pace HIS for atrial fibrillation and heart failure
This study tests a new approach called 'Ablate and Pace HIS' for people with atrial fibrillation and heart failure who haven't improved with other treatments. It combines a heart ablation procedure with a special type of pacing to help your heart pump more efficiently and reduce symptoms.
Leicester, LeicestershireAges 18–100 - NCT06174506Recruiting
Predicting atrial fibrillation in pacemaker patients
This study is looking at whether two blood tests (hs Troponin I and NT-proBNP) can help predict if people with a permanent pacemaker will develop atrial fibrillation, a common heart rhythm problem. If you need a pacemaker, you may be able to join and help researchers learn more.
Ho Chi Minh City, None SelectedAges 18 years+ - NCT06189976Recruiting
Can a quick heart pacing test after TAVI predict pacemaker need?
This study checks if a short, controlled heart pacing procedure right after your TAVI (a valve replacement) can tell doctors whether you might need a permanent pacemaker later. It aims to help avoid unnecessary pacemakers.
BrusselsAges 18 years+ - NCT06356207Recruiting
Measuring heart pause time in fainting during tilt table test
This study tests a new way to measure how long it takes for your heart to pause during a tilt table test, in people with reflex fainting spells. The results may help doctors decide if a pacemaker is right for you.
BolzanoAges 18 years+ - NCT06059638Recruiting
Pacemaker pacing for blood pressure control
This study tests whether adjusting the timing of a pacemaker can help lower blood pressure in people who already have or need a pacemaker. It could be an option for those whose blood pressure is not well controlled with medication.
Scottsdale, ArizonaAges 18 years+ - NCT06561932Recruiting
Leadless pacemaker for heart failure resynchronization
This trial tests a completely leadless pacemaker (WiSE® CRT) for heart failure patients who need cardiac resynchronization therapy (CRT). It aims to avoid the long-term risks of traditional wires (leads) in the heart.
Birtinya, QueenslandAges 22 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+ - NCT06699342Recruiting
Pacing and heart ablation for atrial fibrillation
This trial tests a combination of heart pacing and a specialized ablation procedure in older adults with permanent atrial fibrillation that hasn't improved with other treatments. It aims to improve symptoms and reduce hospital stays related to heart failure.
Seoul, Jongno-guAges 65 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+ - 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 - NCT06814574Recruiting
Pacemaker after tricuspid valve replacement
This study looks at whether people who need a new tricuspid heart valve also need a pacemaker soon after. Researchers want to learn more about heart rhythm changes after valve replacement.
München, BavariaAges Any age - NCT07201363Recruiting
Inflammation and scarring markers after TAVI
This study looks at markers of inflammation and scarring in people who develop heart rhythm problems after having a TAVI procedure (a minimally invasive valve replacement). It may help doctors understand and predict these complications.
Rijeka, CroatiaAges 18 years+ - NCT07209852Recruiting
Pacing the heart's left bundle branch area with a new lead
This trial tests a new pacing lead placed in the left bundle branch area of the heart. It is for people who need a pacemaker for certain slow or irregular heart rhythms.
BrugesAges 18 years+ - NCT07250529Recruiting
Comparing two pacemaker pacing methods for heart block
This study compares two types of pacemaker pacing methods in people with heart block and normal heart pumping function. It looks at how often short bursts of fast heart rhythm occur in the upper heart chambers, which may help improve long-term heart health.
PátraiAges 18 years+ - NCT07342036Recruiting
Study of new heart device leads and tricuspid valve leakage
This study looks at how a new pacemaker or defibrillator lead may affect the tricuspid valve (the valve between the right upper and lower heart chambers). It helps doctors understand if the lead causes leakage (regurgitation) over time.
Bad Oeynhausen, North Rhine-WestphaliaAges 18 years+ - NCT06299514Recruiting
Pacemaker and ablation for heart failure with atrial fibrillation
This trial tests if a pacemaker plus an ablation procedure can improve heart failure symptoms in people with atrial fibrillation. It is for those with moderate to severe heart failure who are already on the right medications.
Victoria, British ColumbiaAges 18 years+ - NCT07356505Recruiting
Micra AV2 pacemaker study for heart block
This study tests a small pacemaker, the Micra AV2, for people with a type of heart block that affects electrical signals between the upper and lower heart chambers. The goal is to see how well and safely the device works.

Common questions
- Are there clinical trials for pacemaker?
- Yes. Clin2 currently lists 79 recruiting pacemaker 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 pacemaker 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 pacemaker 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.
