Abstract:
A system for graphically displaying information received from at least one lead positioned within a passageway of a heart related to an implantable medical device, the system comprising:an analyzer for receiving the electrogram signal from the electrical lead and for locating and marking desired characteristics of the electrogram signal with a plurality of markers to produce a marked electrogram signal; a processor for receiving the marked electrogram signal from the analyzer, for recognizing the marked desired characteristics of the electrogram signal, and for inserting amplitude information into the marked electrogram signal; a display buffer for momentarily capturing a portion of the electrogram signal adjacent to a single marker; updating means for continuously updating the captured portion of the electrogram signal; a selection switch for selecting a selected signal between the electrogram signal received from the electrical lead and the captured portion of the electrogram signal stored in the display buffer; a sensitivity threshold control for controlling a sensitivity threshold; and a display controlled by the processor for displaying the selected signal and for graphically displaying the sensitivity threshold superimposed on the selected signal.
