  • Single complex electrogram display having a sensing threshold for an implantable medical device
    Patent number: 6577896
    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.

  • Single complex electrogram display having a sensing threshold for an implantable medical device
    Patent number: 6266555
    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.
