SYSTEM AND METHOD FOR USING ATRIAL PACING TO ENHANCE FUNCTION OF STUNNED ATRIAL MYOCARDIUM FOLLOWING CONVERSION TO NORMAL SINUS RHYTHM

摘要

An implantable medical device (IMD) includes a therapy circuit for delivering atrial pacing and a control circuit for detecting a return to sinus rhythm, determining the duration of atrial arrhythmia preceding the return to sinus rhythm, and controlling the therapy circuit to deliver transient atrial pacing based on the duration. Further, the implantable medical device comprises means for using data from a hemodynamic sensor to select the pacing rate of the transient atrial pacing. The pacing may be overdrive pacing or paired pacing.
