ST Reference Complex
The averaged ST segment waveform(s) displayed in the ST menu
can be saved as reference complexes. The reference waveforms
can then be superimposed on the current ST segment waveform
to highlight changes in the ST segment since the last save. Upon
saving, the reference complex is time-stamped and available for
display.
WARNIN G: If you change an ECG lead and access the
ST Setup menu, you lose the saved ST reference com-
plex. The saved ST reference complex is retained if you
change a lead and later reselect it without entering the
ST Setup menu.
