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.

ST Alarm

Settings

All IntelliVue Information Center alarm settings (limits and on/off status) have

unit default settings. The IntelliVue Information Center however, lets you set the

high and low ST alarm limits for individual patients based on:

• Your assessment of the patient's clinical condition.

• Unit protocols.

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.
