SYSTEMS AND METHODS FOR RATE RESPONSIVEPACING WITH A LEADLESS CARDIAC PACEMAKER

摘要

Systems and methods for providing rate responsive pacing therapy to a heart of a patient. One example method for providing rate responsive pacing therapy includes sensing cardiac electrical data with a leadless cardiac pacemaker (LCP) that is implanted within or proximate the heart. From this location, the LCP may provide pacing therapy to the heart based at least in part on the sensed cardiac electrical data. An implantable medical device located remotely from the heart may sense patient activity, and may wirelessly communicate patient activity data from the implantable medical device to the LCP, sometimes using conducted communication. The LCP may be then determine an adjustment to the provided pacing therapy (e.g. adjust the pacing rate) based at least in part on the received patient activity data signal.
