Compare two heart pacing options in people with weak heart function
Part of Heart & circulation clinical trials.
This trial compares two types of “left-side” heart pacing to see which one works better in people with weak heart pumping. It may help guide the best pacing choice for improving heart function and symptoms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 18 years or older
- Your heart pumping strength (left ventricular ejection fraction) is 50% or less within the last 6 months
- Your heart’s electrical timing is delayed (QRS ≥130 ms) OR you expect to need a lot of right-chamber pacing (more than 40%) OR you already have a device causing that pacing
- You are on the best standard heart-failure medicines already, or your doctor can work to start and slowly raise them before the pacing procedure
- You should not be pregnant, nursing, or planning pregnancy during the study
- You can do follow-up visits as scheduled and are able to have the required heart tests and imaging (including contrast dye if needed)

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.
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.
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.
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.
This trial tests if a newer pacing method called left bundle branch area pacing works as well as standard cardiac resynchronization therapy (CRT) for people with heart failure and a specific heart blockage (left bundle branch block). It aims to offer an effective treatment option with potentially easier setup.
This study tests a new way to pace the heart to see if it can improve how well the heart pumps. It uses a special Abbott pacemaker to pace a part of the heart called the left bundle branch and adjust the timing to match your natural heart rhythm.
