Introduction
Left bundle branch area pacing (LBBAP) aims to achieve physiological
pacing by capturing the conduction system in the area of the left bundle
branch. LBBAP has exclusively been performed using lumen-less pacing
leads (LLL) with fixed helix design. This study explores the
feasibility, safety and pacing characteristics of LBBAP using
stylet-driven leads (SDL) with an extendable helix design.
