How different pacemaker lead positions affect heart rhythm signals
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older
- Your heart is currently in normal rhythm (not in atrial fibrillation)
- You need a permanent pacemaker with a lead going to your upper heart chamber
- You have not had atrial fibrillation for a long time, or had your heart's natural electrical pathway blocked
- You do not have a previous pacemaker or defibrillator that needs replacement or upgrade
- You have not had a heart attack or severe chest pain in the last 3 months

This trial tests a new pacemaker placement technique for people with a slow heartbeat (sinus node dysfunction) who need a pacemaker anyway. The goal is to see if this special placement can help prevent atrial fibrillation, a type of irregular heartbeat that can cause stroke and other complications.
This study compares two different pacing methods for people who need a pacemaker. It looks at how these methods affect the risk of developing atrial fibrillation (an irregular heartbeat).
This study compares two types of pacemakers: a small leadless pacemaker (placed directly in the heart without wires) and a newer pacing technique called left bundle area pacing. It aims to see which is safer and works better for people who need a pacemaker due to heart block or after a TAVR procedure.
This study compares two ways of placing a pacemaker lead to see if one protects your heart's pumping ability better over time. It may help prevent heart muscle weakness caused by pacing.
This study compares two methods of placing a pacemaker lead to see if one works as well as the other for people who need a pacemaker. It may help improve heart function and reduce symptoms.
This study compares two ways to place a pacemaker lead in the heart for people who have heart failure and a type of irregular heartbeat called atrial fibrillation. The goal is to see which pacing method helps the heart pump blood better.
