8.7.6. Saving the ST Baseline
ST analysis requires valid samples. Set an ST baseline when ST values become stable.
If you do not set a baseline, the monitor will automatically save a set of baselines about 5
minutes after a valid ST measurement appears. You can also manually update the baseline
by selecting 【Set Baseline】 in the lower left corner of the 【ST View】 interface.
You can also make the following settings under the ST interface:
Select 【Show Baseline】 or 【Hide Baseline】 to show or hide ST baseline
segments and parameter values.
Select 【Show Mark】 or 【Hide Mark】 to show or hide ST reference point,
J point and ST point positions.
CAUTION：
Changing the ST baseline will affect the ST alarm.
8.7.7. Entering ST Graphic Window
The steps to enter the ST Graphic window are as follows:
1. Select ECG parameter area, waveform area, ST parameter area or ST
waveform area to enter 【ECG】 menu.
2. Select 【ST View】.
3. Select 【ST Graphic】 from the bottom of the 【ST View】menu.
The following figure shows ST Graphic. The height of the bar represents the ST
value of the corresponding ST lead. The color of the bar indicates the ST alarm status:
green indicates that the ST value is within the normal range; Cyan, yellow and red
indicate that the ST value exceeds the alarm limit. The alarm color corresponds to the
level of ST alarm.
