Observational Study on Left Bundle Branch Area Mapping for Pacemakers

This study is looking at how to best place pacemakers in the Left Bundle Branch Area (a specific part of your heart's electrical system). Researchers will use a 3D mapping tool called NavX during routine pacemaker implantation procedures. They want to understand the electrical and anatomical features of this area to improve how pacemakers are implanted. You could join if you are between 18 and 88 years old and are already scheduled to receive a Left Bundle Branch area pacemaker. The study aims to understand the characteristics of the target area for lead implantation. The current recruitment status is unclear.

Study design
This is an observational study involving 30 patients. It is not a randomized trial and the phase is not specified.
What's involved
You would undergo a standard Left Bundle Area pacemaker implantation. During this procedure, 3D mapping will be performed.
Compensation
Not stated in the trial record.
Follow-up
Electroanatomical characteristics will be measured through study completion, an average of 1 year.
