Recruiting studies
- 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 - NCT05327062Recruiting
Noninvasive mapping to guide a heart resynchronization device
This trial tests a noninvasive way to map your heart’s wiring and veins to help guide placement of a heart resynchronization therapy (CRT) device. If you have certain abnormal heart rhythm and weak heart pumping, it may help doctors place the therapy more accurately and safely.
Chicago, IllinoisAges 18 years+ - NCT05564689Recruiting
Tests coronary blood flow in heart failure patients with CRT
This study measures how well blood flows in the heart (coronary flow) in people with heart failure with reduced pumping strength and a specific heart rhythm problem called left bundle branch block. It focuses on people who already have a cardiac resynchronization therapy (CRT) device and have stable treatment, to see how coronary flow relates to their heart condition.
AalborgAges 18 years+ - NCT05776797Recruiting
Ablation vs best medicines for CRT patients with permanent atrial fibrillation
This trial compares two approaches—an AV junction ablation procedure versus continued best medical treatment—in people who already have a heart device for heart failure (CRT) but still have ongoing permanent atrial fibrillation. It aims to improve how well your heart rhythm is controlled and how effectively the device can pace your heart.
Liberec, Liberec RegionAges 18–85 - NCT05868616Recruiting
Checking heart resynchronization timing with a noninvasive test
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
OsloAges 18–80 - 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+ - 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 - 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+ - NCT06969924Recruiting
How CRT works for adults with congenital heart disease
This study looks at how well cardiac resynchronization therapy (CRT) works for adults who were born with a heart defect. Researchers will review medical records to see if the therapy helps improve heart function.
Leiden, South HollandAges 18 years+ - NCT02814942Recruiting
Testing CRT in people with weak hearts and wide ECG signals
This study looks at whether a device called CRT (Cardiac Resynchronization Therapy) can help people with heart failure who have a weak heart pumping strength and a “wide” electrical signal pattern on an ECG. It may help some people feel better and improve heart function, especially if they are not already on the best standard medicines.
SingaporeAges 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+ - NCT04662970Recruiting
Imaging after a heart device to optimize pacing settings
This study uses a heart MRI (a special scan) to better map the heart’s electrical activity, with the goal of fine-tuning settings on your implanted pacing device. It’s meant to improve how well the device coordinates your heartbeat.
Innsbruck, TyrolAges 18 years+ - NCT07592494Recruiting
Arm Exercise Training for Heart Failure With Device
This study compares different types of arm exercises for people with heart failure who have a pacemaker or defibrillator implanted. The goal is to see which exercise approach best improves how well your arms function and help you stay active.
ÇorumAges 18 years+ - NCT06689111Recruiting
Heart resynchronization method study for patients with LBBB and heart failure
This study compares two ways to resynchronize the heart's pumping in people with heart failure and a specific heart block (LBBB). It uses special ultrasound imaging to see which method works better for improving heart function.
Pátrai, GreeceAges 18–90 - NCT07434193Recruiting
Pacing study after aortic valve replacement
This trial tests if special pacing of the heart's lower chambers (called cardiac resynchronization therapy, or CRT) can help people who develop a new electrical delay in the heart after having a transcatheter aortic valve replacement (TAVI). The study compares two types of pacing to see which works better for recovery.
BudapestAges 18 years+ - NCT07069738Recruiting
New pacemaker vs standard cardiac therapy for heart failure
This study tests a newer type of pacemaker that paces the heart's left bundle branch area, compared to the usual cardiac resynchronization therapy. It is for people with heart failure who need a combined pacemaker-defibrillator (CRT-D) and have a specific heart rhythm pattern (left bundle branch block) with reduced pumping strength.
Huntsville, AlabamaAges 18 years+ - NCT07664189Enrolling by invitation
Left bundle pacing plus CRT vs. LBBP alone
This trial tests a new pacing approach that combines a left bundle branch pacemaker with standard cardiac resynchronization therapy (CRT) for people with heart failure. It aims to improve the heart's pumping efficiency compared to using the left bundle branch pacemaker alone.
Medellín, AntioquiaAges 18 years+ - NCT05265520Recruiting
Pacing strategy study for certain heart failure patients
This trial tests a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
Phoenix, ArizonaAges 18 years+ - 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 - NCT05971225Recruiting

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.

Common questions
- Are there clinical trials for cardiac resynchronization therapy?
- Yes. Clin2 currently lists 26 recruiting cardiac resynchronization therapy 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 cardiac resynchronization therapy 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 cardiac resynchronization therapy 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.
