Pacemaker upgrade study for heart failure
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a pacemaker that paces the right ventricle more than 40% of the time
- Your heart's pumping strength (LVEF) is between 35% and 50%
- Your doctor has recommended upgrading to a special type of pacemaker (CRT) that helps the heart beat more in sync
- You have had at least one sign that your heart failure has worsened since getting the pacemaker, such as a drop in your heart function, an increase in the heart size, higher fluid levels, less activity, or more symptoms

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 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 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 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.
This study tests a new way to guide pacemaker placement using electrical mapping to improve heart pumping in people with heart failure. It may help your heart beat more in sync, which can ease symptoms and improve quality of life.
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.
