Recruiting studies
- NCT06324682Recruiting
Comparing heart pacemaker types for better treatment
This trial looks at different ways to pace the heart (like left, right, or both sides) to see which works best for people who need a pacemaker. If you have a heart condition requiring a pacemaker, this study may help find the safest and most effective option for you.
Ferrara, FEAges 18 years+ - 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+ - NCT05585411Recruiting
Pacemaker type test to reduce heart worsening and death risk
This study compares two pacemaker pacing strategies—left-sided “bundle branch area” pacing versus right-sided ventricular pacing. It aims to see which approach better prevents heart failure getting worse and reduces abnormal timing between heart chambers over time.
Bucheon-siAges 19 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+ - NCT07276490Recruiting
Pacemaker Study for Heart Block
This study tests how a pacemaker affects blood flow and heart health in people with heart block. It aims to see if special pacing settings can improve how the heart works.
Tallinn, HarjuAges 18–80 - NCT05214365Recruiting
Pacing study to help people with heart block avoid stronger harm
This study looks at a heart pacing approach to prevent damage to the heart muscle that can sometimes happen after a pacemaker is placed for atrioventricular (heart rhythm) block. It may help some people avoid worsening heart function over time.
BarcelonaAges 18–100 - NCT07082283Recruiting
Atrial pacing and heart function after cardiac surgery
This study looks at how a short burst of electrical pacing to the upper chambers of the heart affects blood flow and heart function after cardiac surgery. It may help doctors find better ways to support recovery.
BeirutAges 18 years+ - NCT06197503Recruiting
Comparing two types of heart pacing after TAVI
This trial compares two ways to pace the heart after a TAVI procedure for people who need a pacemaker. It aims to find which pacing method works better for preserving heart function.
BarcelonaAges 18 years+ - NCT06241651Recruiting
Comparing two types of pacemakers for heart failure patients
This trial tests if a new pacemaker method (CSP) works better than the standard method (BiVP) for people with heart failure who already have a right ventricular pacemaker and need an upgrade.
Nanjing, JiangsuAges 18–80 - NCT06620705Recruiting
Pacing options for AF with low heart function
This trial compares two types of pacing for people with permanent atrial fibrillation (AF) and a weak heart pump (ejection fraction less than 50%). It tests whether pacing the left bundle branch area works as well as or better than standard biventricular pacing to improve heart function.
Aarhus N, Aarhus NAges 18 years+ - NCT07603648Recruiting
How different pacemaker lead positions affect heart rhythm signals
This study looks at how placing a pacemaker lead (a thin wire) in different spots in the upper heart chamber affects electrical signals. It may help doctors choose the best position for future pacemakers.
Zunyi, GuizhouAges 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+ - NCT06105580Recruiting
Pacing methods for heart failure with wide QRS
This trial compares two ways to pace the heart in people with heart failure and a wide QRS (a sign the heart's electrical signals are slowed). The goal is to see which method better reduces the risks of death, heart failure hospitalization, or needing a heart transplant.
BarcelonaAges 18 years+ - NCT06532786Recruiting
Rhythm-based strength training for brain and muscle
This study tests if using a metronome (a device that keeps a steady beat) during strength training can help your brain adapt better. You'll do exercises while listening to a rhythm to see if it improves how your nerves and muscles work together.
Almada, Monte de CaparicaAges 18–40 - 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+ - 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+ - NCT07759063Enrolling by invitation
Self-paced walking study for stroke or brain injury survivors
This study tests a new way to help people who have had a stroke or brain injury walk with a more even step. It uses a treadmill that adjusts to your own pace, which may improve your walking symmetry.
Omaha, NebraskaAges 19–75 - NCT06088927Recruiting
Long-term results of conduction system pacing
This study looks at how well a special type of pacemaker (conduction system pacing) works over time. If you've already had this procedure, joining could help doctors learn how to improve future care for people like you.
CaenAges 18 years+ - NCT07009834Recruiting
Solving challenges with conduction system pacing
This trial is testing a special way to pace the heart's natural electrical system, which may help people who need a pacemaker for certain heart-block conditions or for heart failure treatment. It aims to make pacing work better.
LondonAges 18–100 - NCT07492979Recruiting
Pacemaker placement study for heart failure
This trial compares two types of pacemaker placement to improve heart function in people with heart failure. One method paces the heart's natural conduction system, while the other paces the lower chambers of the heart. The goal is to find which approach works better for heart resynchronization therapy.
AarhusAges 18–99 - NCT05491655Recruiting
Testing a new pacing approach in some heart failure patients
This study looks at whether a high-intensity “His bundle” heart pacing method can help people with heart failure who have a specific heart rhythm pattern on ECG. It likely aims to improve heart pumping and symptoms in people who are otherwise a good match for an ICD and meet other criteria.
Acquaviva delle Fonti, BariAges 18–90 - NCT05760924Recruiting
Testing a new heart pacing method for CRT nonresponders
This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
TomskAges 18–80 - NCT05769036Recruiting
Biventricular vs left bundle pacing for heart failure outcomes
This trial compares two types of heart pacing to see which improves outcomes for people with heart failure. It may help those who need pacing to better coordinate heartbeats and relieve symptoms.
