BrugesAges 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+ - NCT07118358Recruiting
Testing a new leadless pacemaker for slow heart rhythms
This trial studies a small, leadless pacemaker that is placed directly in the heart to treat slow heart rhythms. It's designed for people who need a pacemaker for the bottom chambers of the heart.
Burlingame, CaliforniaAges 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+ - NCT06159764Recruiting
Registry of nerve-targeting heart treatment for fainting
This registry tracks people who receive a heart procedure called cardioneuroablation to stop severe fainting spells. The procedure targets nerve signals that cause the heart to pause, and researchers want to learn how well it works in real-world patients.
BronAges 18–100 - 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+ - NCT05336877Recruiting
Using Medicare data to study pacemaker care after implant
This study looks at Medicare claims to understand how well different pacemakers work in real-world care after they are implanted. You may be included if you are a Medicare patient who received an Aveir VR leadless pacemaker or a single-chamber ventricular pacemaker after the study began.
Sylmar, CaliforniaAges 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+ - 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+ - 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 - 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+ - NCT04075084Recruiting
Watching outcomes of routine home monitoring after a heart monitor implant
This registry study follows people who get a BIOTRONIK implantable heart monitor and use home monitoring. It looks at how routine care and at-home check-ins work in real life, which may help improve support and tracking over time.
AdelaideAges 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+ - NCT06056817Recruiting
Testing a new pacemaker system
This trial is testing a new type of pacemaker system. It may be an option for adults who need a single-chamber ventricular pacemaker and are generally in good health.
Minneapolis, MinnesotaAges 18 years+ - NCT06052475Recruiting
Pacemaker upgrade study for heart failure
This trial is for people with a standard pacemaker that stimulates the right ventricle most of the time. It tests whether a newer type of pacemaker (CRT) can improve heart function and symptoms. If you have a weakened heart (LVEF between 35-50%) and your heart failure has gotten worse, this study may be a good fit.
CambridgeAges 18 years+ - NCT05935007Recruiting
Study for people with an Aveir DR leadless pacemaker
This study uses your medical records from Medicare to learn how the Aveir DR leadless pacemaker performs in everyday life after it’s implanted. It mainly helps researchers and doctors understand real-world outcomes and care needs.
Sylmar, CaliforniaAges 18 years+ - NCT05719454Recruiting
Pacemaker-based nerve therapy for high blood pressure
This study tests a new pacemaker programming method (nerve therapy) to help lower blood pressure. It may be an option if you need a dual-chamber pacemaker and your blood pressure stays high despite medicine.
PragueAges 18 years+ - NCT05298748Recruiting
Audio recordings to help breathing control mature in preterm babies
This trial studies whether listening to special “womb” sounds can help a preterm baby’s breathing control develop as they grow. It may help babies who are already breathing on their own (with low or no extra oxygen support).
Cleveland, OhioAges 1 week–1 month - NCT05127720Recruiting

Common questions
- Are there clinical trials for bradycardia?
- Yes. Clin2 currently lists 49 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.
