Establishing
ST Reference
Beats
(Baseline)
After adjusting the measurement points, you can establish baseline reference
beats for all available leads in the ST Review window at the IntelliVue
Information Center. Reference beats enable you to compare waveform changes,
for example from admission, or prior to or after treatment. The reference
continues to be saved beyond the 24 hour review window, but you can update it
to any beat within the last 24 hours. Please refer to the
IntelliVue Information
Center Instructions for Use or Online Help for directions.
3 Adjust the J point, if necessary, by placing the cursor over the J-
point button to access the adjustment arrows. Then use the arrows to
position the bar at the end of the QRS complex and the beginning of
the ST segment.
4
Adjust the ST point, if necessary, by using the J point as an
“anchor” and placing the bar at the midpoint of the ST segment.
Choices are J+0, J+20, J+40, J+60, or J+80.
