Bachmann's Bundle Versus Right Atrial Appendage Pacing: A Systematic Review and Meta-Analysis.
BACKGROUND Right atrial appendage (RAA) pacing remains the default atrial lead position despite evidence that non-physiological atrial activation promotes interatrial dyssynchrony. Bachmann's bundle pacing (BBp) targets the interatrial conduction pathway. We evaluated whether BBp improves electrophysiologic markers of...
