- NCT03232918RecruitingPhase 4
Oxytocin effects on baby’s heart rate during labor
This study looks at how oxytocin (a labor-inducing/strengthening medicine) may affect your baby’s heart rate during labor. It also compares what happens when labor pain relief is given as a spinal/epidural injection.
Iowa City, IowaAges 18–55 - NCT05815745Recruiting
Compare two heart pacing strategies for slow heart rhythm
This study compares two types of heart pacing—one that mainly targets the heart’s lower chambers versus one that targets the right side—to see which leads to better outcomes for people needing a pacemaker. It may help improve treatment for certain slow heart rhythm problems that require pacing.
DublinAges 18 years+ - NCT05896592Recruiting
Ablation versus changing pacing settings for slow heartbeats
This study compares a procedure called cardioneuroablation with staying on permanent pacing in people who have symptoms from a slow heart rate. It aims to see which approach works better and is safer for reducing symptoms related to sinus node or heart conduction problems.
Radom, Masovian VoivodeshipAges 18–65 - NCT03008291Recruiting
Heart pacemaker study for slow heartbeats and heart failure
This trial tests how pacing from a specific part of the heart (a “bundle” pacing approach) can affect people with heart failure and/or slow heart rhythms. It may help certain patients whose heart rhythm is too slow or who need a pacemaker and related devices.
Rochester, MinnesotaAges 18 years+ - NCT07468383Recruiting
Catheter ablation for slow heart rate study
This study tests a catheter procedure to treat a slow heart rate (bradycardia) that causes symptoms like dizziness or fainting. It may be an option for people who haven't had a pacemaker and whose heart can still speed up with medication.
Beijing, ChinaAges 18–65 - 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+ - NCT07733960Recruiting
Pacing system study for heart pacing therapy
This trial tests a new pacing system designed to improve how pacemakers work. It may help people who need a pacemaker with left bundle branch area pacing.
Madurai, Tamil NaduAges 18 years+ - NCT07732257Recruiting
Wireless button sensor study for premature infants
This study tests a small, wireless button-like sensor to monitor vital signs in premature infants in the NICU. It may offer a gentler way to track your baby's health.
Montreal, QuebecAges Any age - NCT07501299Recruiting
HeartBeam ECG Registry for heart monitoring
This registry collects ECG data from people who are already getting an ECG for their heart health. It uses a device called HeartBeam to see if it works as well as the standard ECG machine.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07287423Recruiting
A study of a new pacemaker system for heart rhythm problems
This trial tests a new pacemaker system for people who need a pacemaker for a slow or irregular heartbeat. It aims to see if the system is safe and works well.
PragueAges 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+ - NCT04353960Recruiting
Study of heart rate response during eye muscle surgery
This study looks at how the heart rate changes when eye doctors move the eye muscles during strabismus (eye alignment) surgery. It may help doctors better understand and manage this normal reflex during surgery.
Anchorage, AlaskaAges 1 month–100 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+ - NCT05165095Recruiting
Remote monitoring checks for new pacemakers
This trial tests how well remote monitoring features in certain pacemakers work after implantation. It may help your care team spot issues earlier and improve the remote alert system.
KremsAges 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 - 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+ - 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+ - NCT05932602Recruiting
Study of heart pacemaker care under Medicare
This study follows Medicare patients who recently got a specific type of pacemaker to see how coverage works in real life. It may help ensure patients continue to have access to the devices and care they need.
Sylmar, CaliforniaAges 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+ - 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+ - NCT06100770Recruiting
Aveir leadless pacemaker study for Medicare patients
This study looks at how well a new type of pacemaker, called Aveir AR, works for people with Medicare. It helps doctors understand if this leadless pacemaker is safe and effective for treating slow heart rhythms.
Sylmar, CaliforniaAges 18 years+ - NCT06115980Recruiting
Testing a new device for heart device lead removal
This trial tests the safety and early performance of the Xtrac O.S. system, a new tool designed to remove old pacemaker or defibrillator leads. It may help patients who need their leads taken out after being in place for 1 to 5 years.
JerusalemAges 18–85 - 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 - 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.

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.
