Comparing pacemakers for better heart function in heart failure
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have symptoms of heart failure (like shortness of breath or tiredness) and are in New York Heart Association class II, III, or IV.
- Your heart’s pumping ability is reduced – ejection fraction of 40% or less.
- Your ECG shows a wide QRS complex (130 ms or more) with left bundle branch block, OR a very wide QRS (over 150 ms) without left bundle branch block.
- You are already on the best medical therapy for heart failure.
- You are not pregnant (if you could become pregnant, you need a negative pregnancy test).

This study tests a new heart scan method to help doctors place pacemakers more accurately for people with heart failure. It aims to improve the effectiveness of the pacemaker treatment and may lead to better outcomes for patients.
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.
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.
This study compares different ways of pacing the heart to improve its pumping ability in people with heart failure. It aims to find the best pacing method to help your heart work more efficiently and improve symptoms.
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.
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.
