LBBAP
Also written as: LBBAP — Left Bundle Branch Area Pacing
Left bundle branch area pacing technique targeting the conduction system for physiologic ventricular activation.
Full Definition
Left bundle branch area pacing represents an advanced pacing technique that targets the left bundle branch or adjacent septal myocardium to achieve more physiologic ventricular activation compared to traditional right ventricular pacing. This technique involves precise lead placement through the interventricular septum to capture the left bundle branch directly or the septal myocardium in close proximity to the conduction system. LBBAP demonstrates superior electrical and mechanical synchrony compared to conventional pacing and serves as an alternative to cardiac resynchronization therapy in selected patients. Proper documentation requires detailed capture threshold measurements and electrocardiographic morphology analysis.
Usage
Usage note: Document specific capture characteristics and QRS morphology changes with LBBAP.
