Comparison of the Influence of Right Atrial Septal Pacing and Appendage Pacing on an Atrial Function and Atrial Fibrillation in the Clinical Situation.

Introduction: Recently right atrial septal (RAS) pacing is often selected, but the benefit brought by RAS pacing has not been clear. The aim of this study was to evaluate the differences between RAS pacing and right appendage (RAA) pacing.

Methods: 223 consecutive new patients with a right atrial (RA) electrode during the period from January 2004 to December 2012 were studied retrospectively.
