NCT06509763

Brief Summary

The goal is to validate the resynchronization criteria with a non-invasive technique, during the LBBP implant. Non-invasive real-time ventricular activation maps will be created and analyzed before, during, and after the implantation of the left bundle branch lead, including right septal pacing, mid and deep septal pacing and pacing when reaching the left bundle branch according to the published standard LBBP criteria. Using these maps, the investigators will quantify activation times and evaluate changes in the ventricular sequence during implantation.
