Recruiting studies
- 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 - NCT07809347Recruiting
Factors linked to slow heart rate after pulsed field ablation
This study looks at why some people have a slower heart rate after a heart procedure called pulmonary vein isolation using pulsed field ablation (PFA). It aims to find out what factors might make this more likely, which could help doctors predict and manage it better.
Wroclaw, Lower Silesian VoivodeshipAges 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 - 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 - NCT06852053Recruiting
New tool to predict breathing pauses in premature babies
This study is testing a new tool that may help predict when babies born very early might have breathing pauses or slow heart rates. By using this tool, doctors hope to better monitor and care for your baby.
Birmingham, AlabamaAges 5 months–7 months - 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+ - 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+ - 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.
DüsseldorfAges 18–80 - 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 - 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+ - NCT07820072Recruiting
Temporary pacemaker safety and performance study
This study tests a temporary pacing wire that helps control heart rhythm during procedures or when the heart beats too slowly. It aims to see if the device works well and is safe for people who need short-term pacing.
Acquaviva delle Fonti, BariAges 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 - 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 - 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 - NCT07589452Recruiting
Pacemaker heart rate settings and blood pressure in older adults
This study tests whether a specific pacemaker heart-rate setting helps control blood pressure and improve heart function in adults over 65 with slow heartbeats and high blood pressure. You would receive a dual-chamber pacemaker (a standard treatment) and be monitored to see how the rate setting affects your health.
Taiyuan, ShanxiAges 65 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+ - 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+ - 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+ - 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+ - 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+ - NCT07342608Recruiting
Study of a new pacing lead for the heart's septum
This study tests a new pacing lead designed to be placed in the wall between the heart's lower chambers (septum). It aims to see if this lead is safe and works well for people who need a new pacemaker.
GhentAges 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 - 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.

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.
