Pacemaker study for heart failure with low heart rate
Part of Heart & circulation clinical trials.
This trial tests a special pacemaker setting to help your heart beat faster during exercise. It may improve your ability to be active if you have heart failure with preserved ejection fraction (HFpEF) and a low resting heart rate.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have heart failure symptoms that make daily activities a little harder (at least NYHA class II).
- You have a type of heart failure called HFpEF, where your heart pumps normally but is stiff. Your doctor will check your ejection fraction (≥50%).
- You are 18 or older and have been hospitalized for heart failure before.
- You can do an exercise test on a treadmill or bike.
- Your resting heart rate is low (below 65 bpm if you have normal rhythm, or below 70 bpm if you have atrial fibrillation).
- You are not taking beta-blockers, digitalis, or certain calcium channel blockers.

This study looks at how the heart muscle works in people with a type of heart failure where the heart pumps normally but doesn't fill properly. It aims to understand the cause better, which could lead to new treatments.
This study tests a pacemaker-based therapy designed to improve heart failure symptoms in people who have a type of heart failure where the heart pumps normally but doesn't relax properly. If you're getting a pacemaker for another reason and have heart failure with preserved pumping function, this could be an option.
This trial tests whether adjusting the lower rate of an already-implanted pacemaker can improve symptoms and exercise capacity in people with heart failure with preserved ejection fraction (HFpEF), a condition where the heart pumps normally but is too stiff to fill properly.
This study tests a new pacing approach for people with a specific type of heart failure (HFpEF) to see if it can improve symptoms and quality of life. It involves a pacemaker-like device that adjusts heart rate based on your needs.
This study tests whether optimized pacemaker settings can improve heart function and symptoms in heart failure patients who need a pacemaker for a slow heartbeat. The goal is to find the best way to program the pacemaker to help your heart work better.
This trial tests whether a special pacing pattern can strengthen your heart's pumping ability. You may qualify if you have heart failure with a low ejection fraction and already have a pacemaker or defibrillator with an atrial lead.
