The Role of Paced QRS Morphology in Determining Initial Site for Lead Placement in Left Bundle Branch Area Pacing

Key Points

• The study aims to identify the influence of paced QRS morphology on lead placement in left bundle branch area pacing.
• Examined the interventricular septum for lead placement
• Analyzed electrocardiographic outcomes
• Assessed aVL/aVR discordance to define target zones
• Identified the interventricular septum as a favorable site for lead placement
• Established that similar electrocardiographic outcomes can be achieved from different sites
• Highlighted the inferior part of the septum as the easiest for lead implantation
