Reliable ST monitoring cannot be ensured under the following situations:
■
You are unable to get a lead that is not noisy.
■
Arrhythmias, such as atrial fib or flutter, cause irregular baseline.
■
The patient is continuously ventricularly paced.
■
The patient has left bundle branch block.
In these cases, you may consider switching off ST monitoring.

Displaying ST Numerics
To display ST numerics and Segments, follow this procedure:
1.
Access
Tile Layout
by either of the following ways:
◆
Select the
Screen Setup
quick key
→
select the
Tile Layout
tab.
◆
Select
Main Menu
quick key
→
from the
Display
column select
Tile Layout
.
2.
Click the numeric area where you want to display the ST numerics, and then select
ECG
→
ST
.
The display of ST parameters area is different according to the lead type:
■
When you are using the 3-lead ECG leadwires, the ST numeric area does not display. A ST value displays in
the ECG numeric area.
■
When you are using the 5-lead ECG leadwires, the ST numeric area displays 7 ST values: ST-I, ST-II, ST-III, ST-
aVR, ST-aVL, ST-aVF, ST-V.
■
When you are using the 6-lead ECG leadwires, the ST numeric area displays 8 ST values: ST-I, ST-II, ST-III, ST-
aVR, ST-aVL, ST-aVF, ST-Va, ST-Vb.
■
When you are using the 12-lead ECG leadwires, the ST numeric area displays12 ST values: ST-I, ST-II, ST-III,
ST-aVR, ST-aVL, ST-aVF, ST-V1, ST-V2, ST-V3, ST-V4, ST-V5, ST-V6.
This example shows the ST numeric area when 5-lead ECG cable is used. Your monitor screen may look slightly
different:
