Pacing methods to protect heart function
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- Your heart's main pumping chamber is working at least 40% of normal (mild or no weakness).
- You need a pacemaker because your heart's electrical signal is blocked (high-degree AV block) and you'll likely need pacing more than 80% of the time.
- Your doctor expects you to live at least one more year and you agree to follow the study plan.
- You do not already need a defibrillator (ICD) or a special heart resynchronization device (CRT).

This study looks at how different pacing methods affect heart function using MRI and advanced ECG imaging. It aims to find the best pacing approach for people with slow heart rhythms who need a pacemaker.
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.
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.
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.
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 study compares two pacing methods to help your heart beat in sync. If you need a cardiac resynchronization therapy (CRT) device, this trial will see if a newer pacing method is just as good as the standard one.
