  • Trigger enhanced electrogram display for positioning an implantable medical device
    Patent number: 6161039
    Abstract: The present invention relates to a graphical display method and apparatus representing 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 an electrogram signal received from at least one lead position within a passageway of a heart. The analyzer produces a marked electrogram signal. A processor receives the marked electrogram signal from the analyzer and recognizes the marked desired characteristics of the electrogram signal. A display, controlled by the processor, displays information representing a portion of the electrogram signal adjacent to the marked desired characteristics of the electrogram signal.
