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.
