Estimating the term…
An implantable pacemaker continuously records pacing events and their respective rates of occurrence in sequence, as they occur, into an Event Record stored in a circular buffer. The circular buffer always contains the most recent events and rates collected. The recording of the pacing events selectively occurs at every event, or at sampling rates of one event per fixed sample interval. A programming device, coupled to the implantable pacemaker through a telemetry link, selectively retrieves the recorded pacing events and rates from the Event Record and reports subsets thereof in condensed or summarized form using numerical and/or graphical formats. The pacing event data collected in the Event Record is three-dimensional in that each pacing event includes a pacemaker event, an associated pacemaker or heart rate, and a real time interval. The programming device also calculates and reports statistical information from the data collected in the Event Record. The Event Record provides a base recording that establishes the behavior of the pacemaker in a particular patient under ascertainable conditions.
A method for operating a pacing system, said pacing system comprising An external device and an implantable pacemaker, for reporting a sequential series of pacing events that occur within said implantable pacemaker, said external device having a display, a memory, and telemetry means for establishing a telemetric link with said pacemaker, said pacemaker having means for pacing a patient's heart, said pacemaker further having means for detecting the occurrence and rate of a plurality of specified pacing events and sequentially recording the occurrence and rate of each event in the order in which it occurs in an event record, said event record being stored in a memory buffer within said pacemaker, said pacemaker further having a telemetry circuit coupled to said memory buffer for selectively telemetering data from said memory buffer to said external device, said method comprising:
A method for operating a pacing system for reporting a sequential series of pacing events, said pacing system comprising an implantable cardiac pacemaker and an external programmer, said pacemaker having means for pacing a patient's heart, a memory, means for detecting a plurality of specified pacing events, and means for recording in said memory, said external programmer having means for retrieving from said memory of said pacemaker, means for processing, and a display, said method comprising:
