摘要： An apparatus and method for normalizing waveform information displayed on a medical device. This waveform normalization allows the user to quickly adjust individual waveforms if they exceed the normal viewing range on the display. An electrogram signal is received from an implantable medical device. The electrogram signal is continuously transformed into a plurality of voltage data samples. A waveform is created from the plurality of voltage data samples, and the waveform is displayed on a medical display device. A user selectable waveform normalization control is located adjacent each displayed waveform on the medical display device. Upon activation of the waveform normalization control, the adjacent waveform is normalized to a pre-determined nominal height on the display.

摘要： 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.
