Abstract
The disclosure pertains to a graphical display method and apparatus relating to an electrogram signal received from at least one lead used in conjunction with an implantable medical device. Specifically, the disclosure provides a time-expanded waveform of a portion of a signal relating to a single heartbeat. Sensitivity threshold information is also graphically displayed on the waveform. Further, a programmer assembly comprises an analyzer for locating marking desired characteristics of the electrogram signal with a plurality of markers to produce a marked electrogram signal. A processor receives the electrogram signal from the analyzer and recognizes the marked desired characteristics of the electrogram signal. The processor also receives sensitivity threshold information from a particular lead. A display, controlled by the processor, graphically displays information representing a portion of the electrogram signal immediately adjacent to a single marker and graphically displays a sensitivity threshold superimposed onto the portion of the electrogram signal.
