Abstract

The present disclosure provides a cardiac pacing system. The cardiac pacing system includes a right atrial ring electrode, a right atrial tip electrode, a right ventricle ring electrode, and a pacing integrated circuit (IC) including a first pace output node electrically coupled to the right atrial ring electrode, a pace return node electrically coupled to the right atrial tip electrode, and a second pace output node electrically coupled to the right ventricle ring electrode, wherein the pacing IC has a fast discharge configuration that facilitates reducing or eliminating a DC rectification current generated from RF interference during a fast discharge phase.
