Recruiting studies
- NCT05283603Recruiting
Registry study for people with left bundle branch block
This is an observational registry that collects health information from people who have a heart rhythm pattern called left bundle branch block. It may help doctors better understand causes, outcomes, and care needs for people with this ECG finding.
SassariAges 18 years+ - NCT04293471Recruiting
Echocardiogram test to predict outcomes in CRT patients
This trial looks at how well an echocardiogram (ultrasound of the heart) can predict outcomes for people with left bundle branch block who already have cardiac resynchronisation therapy (CRT). If you qualify, your heart scans may be used to better estimate risk and guide care.
Tromsø, TromsAges 18–100 - 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+ - NCT07814612Recruiting
Guided pacing for heart failure with left bundle branch block
This study tests a new way to place a pacemaker lead inside the heart to help it beat more effectively, aiming to improve heart function and symptoms in people with heart failure and a specific electrical problem (left bundle branch block). If you meet the criteria, this could be an option to discuss with your heart doctor.
Nanchang, JiangxiAges 18–80 - NCT07791407Recruiting
Heart imaging to guide defibrillator placement in heart failure
This study uses an MRI scan of the heart to better identify which people with heart failure need a defibrillator along with a special pacemaker (cardiac resynchronization therapy). The scan may help doctors decide if the device could improve your heart's pumping and reduce risks.
Madurai, Tamil NaduAges 18 years+ - 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+ - 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+ - 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 - NCT07608822Recruiting
Dual-chamber pacemaker with specialized heart block pacing
This study follows patients who recently received a dual-chamber pacemaker (a device that helps regulate heartbeat) designed to work differently when the heart's electrical signals are delayed or blocked. The trial checks whether this new pacing approach safely reduces irregular heart rhythms and works well over time.
Ústí nad LabemAges 18–18 - NCT07534917Recruiting
New Pacemakers and Heart Function Study
This study compares newer pacemaker types to see how well they work and how they affect your heart's pumping ability and valve function over a short period. You'll be monitored closely with heart imaging to understand which pacemaker performs best.
LondonAges 18 years+ - 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+ - NCT07430553Recruiting
Comparing pacemakers for better heart function in heart failure
This trial compares three types of advanced pacemakers (cardiac resynchronization therapy devices) to see which works best for improving heart function and reducing abnormal heart rhythms in people with heart failure.
London, Greater LondonAges 18 years+ - NCT06707662Recruiting
Pacing methods to protect heart function
This trial tests two pacing approaches to see which one better prevents weakening of the heart's main pumping chamber. It's for people who need a pacemaker for a slow heart rhythm and are expected to rely on it heavily.
BarcelonaAges 18 years+ - NCT07372196Recruiting
Left bundle branch pacing after myectomy for hypertrophic cardiomyopathy
This trial is testing a new way to pace the heart (left bundle branch pacing) for people with hypertrophic cardiomyopathy who still have a dangerous heart rhythm problem after myectomy surgery. It aims to see if this pacing can reduce the risk of sudden cardiac death.
Novosibirsk, Novosibirsk OblastAges 18–75 - 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+ - NCT07342036Recruiting
Study of new heart device leads and tricuspid valve leakage
This study looks at how a new pacemaker or defibrillator lead may affect the tricuspid valve (the valve between the right upper and lower heart chambers). It helps doctors understand if the lead causes leakage (regurgitation) over time.
Bad Oeynhausen, North Rhine-WestphaliaAges 18 years+ - NCT07314008Recruiting
Comparing pacing methods for slow heartbeat with long AV delay
This trial tests two types of heart pacing to see which works better for people with a slow heartbeat from sinus node issues and a long delay between the upper and lower heart chambers (PR interval over 200 ms). The goal is to find the best way to pace the heart while keeping unnecessary pacing minimal.
Seoul, Songpa-guAges 18 years+ - NCT07254013Recruiting
LBBAP Pacemaker Monitoring with Portable ECG
This study is testing a portable heart monitoring device to help doctors check how well a special pacemaker (LBBAP) is working. It may help people who need a new or upgraded pacemaker or heart device.
Besançon, FranceAges 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+ - NCT07236489Recruiting
New pacing method after TAVI for heart block
This trial compares a newer pacing technique (left bundle branch area stimulation) with standard pacing in people who need a pacemaker after TAVI (a valve replacement procedure). It aims to see if the newer method works better for keeping the heart's rhythm stable.
Brest, FinistèreAges 18 years+ - NCT07217392Recruiting
