Waveform normalization in a medical device

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.
