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.

Single complex electrogram display having a sensing threshold for an implantable medical device

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.

The present invention discloses a method of and a system for transferring information from an implantable medical device to a remote location. The system includes a first extensible mark-up language converter for converting information related to the implantable medical device from an initial format to an extensible mark-up language format. A programmer is electrically connected to the implantable medical device and is capable of temporarily saving selected information related to the implantable medical device and capable of transferring the selected information to a remote location. A second extensible mark-up language converter located at the remote location is connected to the programmer and converts the selected information from the extensible mark-up language format to a final format. The selected information can then be manipulated at the remote location.

System and method for transferring information relating to an implantable medical device to a remote location

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. The displayed waveform permits a user to quickly and confidently analyze a specific waveform to determine whether a lead is properly positioned prior to attachment of the implantable medical device.
