Finding the Best Pacemaker Rate for Heart Failure
Part of Heart & circulation clinical trials.
This study tests whether adjusting the pacing rate on a special pacemaker (CRT or conduction system pacing) can improve heart function and daily symptoms in people with atrial fibrillation and heart failure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a history of ongoing or long-lasting atrial fibrillation.
- You have a CRT or conduction system pacing device placed between 3 months and 5 years ago.
- Your heart's natural electrical pathway is blocked or has been intentionally blocked (AV node ablation) within the last 3 months to 5 years.
- Your heart's pumping strength (LVEF) is 50% or higher.
- You have symptoms of heart failure (like shortness of breath or fatigue) that affect your daily activities.

This trial tests whether a procedure that regulates your heart rhythm (pacing) works better than medication for people who have permanent atrial fibrillation, heart failure with a normal pumping strength, and were hospitalized for heart failure in the past year.
This study compares two treatments for people with atrial fibrillation and heart failure: one is a procedure to fix the irregular heartbeat (AF ablation), and the other involves a different type of pacing for the heart. It aims to find which approach helps you feel better and stay out of the hospital.
This trial studies whether a strategy to regularize (control) heart rate can improve outcomes in people who have permanent atrial fibrillation and heart failure. It focuses on people with recent heart-failure hospitalization and checks several heart, kidney, and health-condition limits to keep the study safe.
This trial tests two types of heart pacing procedures for people with heart failure and atrial fibrillation (irregular heartbeat). One approach involves disabling the natural electrical pathway between the upper and lower heart chambers and using a pacemaker to regulate heartbeats; the other uses a special pacemaker that helps both chambers work together. The goal is to reduce symptoms and hospitalizations.
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 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.
