Recruiting studies
- NCT06288633Recruiting
Heart nerve ablation for slow heart rhythm
This test uses a procedure to ablate (destroy) specific nerves in the heart that may be causing your heart to beat too slowly. The goal is to help your heart speed up naturally when needed, so you may avoid needing a permanent pacemaker.
Saint PetersburgAges 18–65 - NCT06453850Recruiting
New catheter for pacemaker lead placement in the septum
This trial tests a new thin tube (catheter) used to guide a pacing wire into the wall between the heart's lower chambers, called the septum. It may be a good option if you need a first-time pacemaker or CRT-D implant and your heart's pumping function is fairly good.
CoimbraAges 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+ - NCT06503016RecruitingPhase 3
Phosphocreatine for medical emergency team patients
This study tests if a medicine called phosphocreatine helps people in the hospital who have a serious heart or lung emergency. It aims to see if the medicine can improve recovery and prevent further complications.
MilanAges 18 years+ - NCT06540521Recruiting
Heart device holter study for LBBAP patients
This study uses a special wearable device to record your heart's electrical signals. It is for people who have a pacemaker or CRT-P with a specific type of lead (LBBAP) and wants to check how well the therapy is working.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06568770RecruitingPhase 2/Phase 3
Comparing two nerve blocks for femur fracture surgery pain
This trial tests if one type of nerve block (PENG block) works better than another (S-FICB) for controlling pain during and after femur fracture surgery. Both blocks are guided by ultrasound to help with your recovery.
Sahiwal, Punjab ProvinceAges 20–70 - NCT06641362Recruiting
Ultra-high frequency ECG for heart timing problems
This study tests a new, more detailed type of ECG (called UHF-ECG) to see if it can better detect uneven electrical timing in the heart. If you are getting your first pacemaker for a slow heart rate or heart failure, this study may help doctors personalize your treatment.
Avondale, ArizonaAges 18 years+ - NCT06854484Recruiting
AVEIR leadless pacemaker UK registry study
This study is an observational registry for people who have or will receive an AVEIR leadless pacemaker. It collects information to help doctors understand how the device performs over time.
London, UKAges 18 years+ - NCT07018648Recruiting
Testing a wearable heart monitor for rhythm problems
This trial tests a chest belt that works with your smartphone to track heart rhythms. It may help if you have or might have an irregular heartbeat.
Olomouc, CzechiaAges 18 years+ - NCT07196397Recruiting
Polish Registry of Heart Nerve Procedures
This registry tracks people who have had or plan to have a procedure that changes the nerves controlling heart rate, such as cardioneuroablation. It aims to better understand and treat conditions like inappropriate tachycardia, POTS, and fainting spells.
RzeszówAges 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+ - NCT07217392Recruiting
Study on pacing the left bundle branch area of the heart
This study tests a new way to place a pacemaker lead in the left bundle branch area of the heart. It may help people who need a pacemaker to see if this approach is safe and works well.
Rio de Janeiro, Rio de JaneiroAges 18 years+ - NCT07221682RecruitingPhase 2/Phase 3
Comparing two nerve block methods for lower leg surgery
This study compares two ways of giving a nerve block (fascia iliaca block) to help with positioning for spinal anesthesia and pain relief after lower leg surgery. The goal is to see which method works better for making patients more comfortable.
Sāhīwāl, Punjab ProvinceAges 30–60 - NCT07254013Recruiting
LBBAP Pacemaker Monitoring with Portable ECG
This study is testing a portable heart monitoring device to help doctors check how well a special pacemaker (LBBAP) is working. It may help people who need a new or upgraded pacemaker or heart device.
Besançon, FranceAges 18 years+ - NCT07290595RecruitingPhase 2/Phase 3
Comparing two medicines for faster nerve block in arm surgery
This study compares two medicines (dexmedetomidine and dexamethasone) added to a numbing drug (ropivacaine) for a nerve block in the collarbone area. The goal is to see which combination works faster and better for pain relief during upper limb surgery.
Sāhīwāl, Punjab ProvinceAges 18–70 - 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+ - NCT07556133Recruiting
Comparing two sedation medicines during cataract surgery
This study tests two sedation medicines (dexmedetomidine and propofol) used to keep patients calm and comfortable during cataract surgery. Researchers want to see which combination works best and is safest for this common procedure.
BeirutAges 18 years+ - NCT07563153Recruiting
Pacemaker Pacing Strategies for Heart Failure Patients
This study tests whether optimized pacemaker settings can improve heart function and symptoms in heart failure patients who need a pacemaker for a slow heartbeat. The goal is to find the best way to program the pacemaker to help your heart work better.
Seoul, SeoulAges 19 years+ - NCT07585799Recruiting
Heart Pacing Method for Wide QRS Rhythm Patients
This trial compares two ways to place a heart pacemaker in patients with an abnormally wide heartbeat pattern. Researchers want to see if a newer pacing technique that targets the heart's natural conduction system works better than traditional pacing methods.
Granada, AndalusiaAges 18 years+ - NCT07671898Recruiting
Freezing vs. Radiofrequency for Slow Heart Rate
This trial compares two procedures to treat very slow heart rates without needing a pacemaker. One uses freezing (cryoablation) and the other uses radiofrequency energy to target nerves that control heart rate.
Tomsk, Tomsk OblastAges 18–60 - NCT03360227Recruiting
Registry after heart device implantation planning
This is a registry study that records information from people before they get a heart-related device implanted. It may help doctors understand how the team’s tests and planning relate to the procedure and outcomes later on.

Common questions
- Are there clinical trials for bradycardia?
- Yes. Clin2 currently lists 45 recruiting bradycardia 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 bradycardia 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 bradycardia 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.
