8.7.5 Entering the ST View
In ST View mode a complete QRS segment for each ST lead is displayed. The color of the current ST segments
and ST deviation values is consistent with the color of the ECG waveforms, normally green. The color of the
baseline ST segments and ST deviation values is white.
To enter the ST View, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the ECG dialog.
2. Select the ST tab.
3. From the bottom of the dialog, select ST View.
8.7.6 Saving the Current ST Deviation and Segment as Baseline
ST deviation is typically monitored as a relative change from a baseline value. Set an ST baseline when ST
deviation values become stable. If you did not set the ST baseline, the monitor automatically saves the baseline
when valid ST deviation values appear for 5 minutes. To set the ST baseline, follow this procedure:
1. From the ST View, select Set Baseline.
2. From the pop-up dialog box, select OK to set the current ST segments and values as the baseline.
From the ST View, you can also perform the following operations:
Display or hide ST baseline by selecting Display Baseline or Hide Baseline.
Display or hide the position of ISO point, J point and ST point by selecting Display Marker or Hide Marker.
CAUTION
Updating ST baseline affects ST alarms.
8.7.7 Entering the ST Graphic
To display ST Graphic, follow this procedure:
1. Select the ECG numeric area or waveform area to enter the ECG dialog.
2. Select the ST tab.
3. Select ST Graphic.
The following figure shows the ST Graphic when ST Alarm Mode is set to Absolute. The height of the bar
indicates the ST deviation value of corresponding ST lead. The color of the bar indicates ST alarm status: green
indicates that corresponding ST deviation value is within alarm limits; cyan, yellow and red indicate that the ST
deviation value exceeds the alarm limits. The color matches ST alarm priority.
(1) ST lead (2) Current ST deviation value
(3) Baseline ST deviation value (4) 1 mV scale
(5) Current ST segment (green) and baseline ST segment (white)
