Heart Pacemaker Placement to Prevent Irregular Heartbeat

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 looks at how placing a pacemaker lead (a thin wire) in different spots in the upper heart chamber affects electrical signals. It may help doctors choose the best position for future pacemakers.

This study is testing two new ways of pacing the heart to see if they can reduce the chance of developing atrial fibrillation (an irregular heartbeat). It might be a good fit if you need a pacemaker for a slow heart rate but have never had atrial fibrillation before.

This trial compares two ways to place a heart pacemaker in patients with an abnormally wide heartbeat pattern. Researchers want to see if a newer pacing technique that targets the heart's natural conduction system works better than traditional pacing methods.

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 compares two heart pacing approaches to see which one better helps prevent atrial fibrillation (an abnormal heart rhythm). It is for people who need a pacemaker and have a prolonged delay between the upper and lower heart chambers.
