Pacing to improve heart function study
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- Your doctor has approved you for a pacemaker that paces both the upper and lower chambers or for a special heart failure pacing device (CRT).
- You have a type of heart block called left bundle branch block (LBBB) or a delay in the heart's electrical signals (IVCD).
- Your natural heart electrical signal (QRS) is 130 milliseconds or longer.
- Your heart's own timing (PR interval) is 250 milliseconds or less.

This study tests a new way to pace the heart (using a specific spot called the Bachmann bundle) to prevent new episodes of atrial fibrillation (an irregular heartbeat) in people with heart failure who already need a pacemaker or defibrillator. The goal is to keep the heart's rhythm more stable and reduce the risk of future heart rhythm problems.
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.
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.
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 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.
