ST point; when the patient's heart rate is less than or equal to 120bpm the system will select J+80 to
locate the ST point.
8.7.10 ST View
ST View displays a complete QRS waveform segment of each ST lead. You can enter [ST View] to view these ST
segments. The color of the current ST segment and ST value is the same as the color of the ECG waveform, usually
green. The ST baseline segment and baseline value are white.
You can enter the [ST View] screen by selecting the ST segment waveform area or through the following steps:
1) Select the ECG parameter area, waveform area or ST parameter area to enter [ECG] menu.
2) Select [ST] tab.
3) Select [ST View] button at the bottom of the menu.
8.7.11 Save ST Baseline
A valid template is required for ST segment analysis, so please set the ST baseline after the ST value is stable. If you
do not set the baseline, the monitor automatically saves a set of baselines after valid ST measurements start for 5
minutes. You can select [Set Baseline] in [ST View] to update the baseline manually.
You can also make the following settings in the ST View screen:
 Select [Display Baseline] or [Hide Baseline] to display or hide the ST baseline segment and parameter value.
 Select [Display Marker] or [Hide Marker] to display or hide the position of ISO point, J point and ST point.
CAUTION
 Change of ST baseline will affect ST alarm behavior.
8.7.12 Enter ST Graphic Window
1) Select the ECG parameter, waveform, ST parameter or ST segment waveform area to enter [ECG] menu.
2) Select [ST] tab.
3) Select [ST Graphic] at the bottom of the menu.
The figure below shows the ST Graphic when [ST Alarm Mode] is set to [Absolute]. The upper semicircle
indicates limb leads: I-II-III-AVF-AVR-AVL, and the lower semicircle indicates chest leads: V1-V2-V3-V4-V5-V6.
The green diagonal line’s drawing indicates the ST real-time value. The vertical center axis is 0mV. When the
ST value is in the range of 0~2.5mV, it is drawed from the vertical center axis anticlockwise to the right. When
the ST value is in the range of -2.5mV~0, it is drawn from the vertical axis clockwise to the left:
