Conduction System Pacing
Also written as: CSP — Conduction System Pacing
A pacing technique that targets the cardiac conduction system rather than ventricular myocardium. Includes His-bundle and left bundle branch area pacing.
Full Definition
Conduction system pacing encompasses advanced pacing techniques that directly stimulate components of the cardiac conduction system, including the His bundle, left bundle branch, and nearby conducting tissue. This approach aims to preserve physiological ventricular activation patterns and avoid the dyssynchrony associated with traditional right ventricular pacing. Conduction system pacing requires specialized tools and techniques to navigate to target sites and achieve stable capture of conducting tissue. The method has gained prominence as an alternative to cardiac resynchronization therapy and for patients requiring high-burden ventricular pacing. Success depends on individual anatomy and the presence of conduction system disease.
Usage
Usage note: Represents a shift from traditional pacing paradigms. Requires specialized expertise and tools.
