  • PACEMAKER WITH DIAGNOSTIC INTRINSIC BEAT SEARCH
    Publication number: 20180256908
    Abstract: Regulating cardiac activity may include pacing the patient's heart at a starting pacing rate and instigating an intrinsic heart beat search algorithm that includes pacing at a reduced rate for a period of time and capturing electrical signals representative of cardiac electrical activity while pacing at the reduced rate in order to determine a presence or absence of intrinsic heart beats. If intrinsic heart beats are not detected, the heart may be paced at a further reduced rate for a period of time. If intrinsic beats are detected, the heart may be paced again at the starting pacing rate. This may continue until intrinsic heart beats are detected or until a lower search rate limit is reached. Diagnostic data may be collected at each stage and transmitted to a display device for analysis by a physician or the like.

  • SYSTEMS AND METHODS FOR RATE RESPONSIVE PACING WITH A LEADLESS CARDIAC PACEMAKER
    Publication number: 20180229043
    Abstract: 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.
