Abstract
The present invention discloses 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. The present invention 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. The programmer assembly of the present invention comprises an analyzer for locating and 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.
