Implantable cardiac stimulation device providing IEGM with reduced respiration modulation effect and method

摘要

An implantable cardiac stimulation device provides an intracardiac electrogram with reduced respiratory modulation effect. The device includes a sensing circuit that senses cardiac activity and provides an intracardiac electrogram signal extending over a plurality of cardiac cycles, a respiration monitor that monitors respiration associated with the sensed cardiac activity, and a cardiac cycle selector that selects a set of intracardiac electrogram cardiac cycles of the plurality of cardiac cycles in response to the monitored respiration. A processing circuit processes the selected set of intracardiac electrogram cardiac cycles to provide the intracardiac electrogram with reduced respiratory modulation effect.
