4. Discussion
The findings of this prospective study can be summarized as follows: First, unipolar pacing from an inserted lead stylet and from the lead connector pin demonstrated similar performance and pacing characteristics (EGM quality, pacing impedance, paced QRS morphology). Secondly, implementation of continuous unipolar stylet pacing during LBB lead implantation is feasible, safe and facilitates the transseptal positioning of stylet driven pacing leads.
