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.
STEPS: Displaying the ST Reference Complex
1. Click on the ST parameter box.
2. Click on
Ref to turn the display of the reference complex ON or OFF.
STEPS: Saving the ST Reference Complex
1. Click on the ST parameter box.
2. Click on
Save. Date and time of saving appear next to the Save option.
NOTE: If you change an ECG lead and access the ST Setup menu, you lose the saved
ST reference complex. The saved ST reference complex is retained if you change a lead
and later reselect it without entering the ST Setup menu.
