Patient Monitor User Manual Monitoring ECG
- 81 -
Differential: The monitor triggers the alarm according to the change of ST. The user does not
need to set alarm for each ST separately, but only need to set alarm switch, alarm level and alarm
difference value (-0.1~0.1) for all ST.
When ST Alarm Mode is differential, the user needs to select Delay to set the ST alarm delay
time. 3 seconds and 5 seconds are optional, and the default is 3 seconds. Besides, the Difference
and baseline value shall be set, the difference range is 0.01 mv ~0.1 mv, and the baseline range is
-1.90 mv ~1.90 mv.
9.8.6 ST View
The ST View displays a complete QRS segment for each ST lead. The color of current ST
segment and ST value are consistent with the color of HR. The color of baseline and ST value are
yellow. To enter ST view, please select ST View in ST Analysis.
In the ST View interface, the user can save ST baseline through clicking Save as Base when ST
values gets stable. If no ST baseline is saved, the monitor automatically saves the baseline when
the first valid and complete ST waveform appears.
In the ST View interface, the user can display the current waveform, baseline waveform, or the
both by selecting Real, Baseline or Real+Base. The user can also hide or display ST points by
selecting Hide Points or Show Points. Besides, the user can record and print the ST view.
In the ST View interface, the user can save ST segment through clicking Save ST SEG. Up to 20
groups of ST segments can be saved. When the 21
st
ST segment is saved, the earliest ST segment
will be deleted.
NOTE:
The ST baseline and ST segment will be cleared in following situations:
1) Turning off the monitor;
2) Changing the electrode type;
3) Changing the calculation lead in 3 electrodes;
4) Entering or exiting Demo mode;
5) Changing the patient type;
6) Admitting new patients;
In order to view the ST value situation of each lead more intuitively, the user can enter into the
ST Histogram. The horizontal axis shows the lead name while the vertical axis shows the ST
value. And the bar graph is used to display the ST value result. The ST histogram refreshes with
ST View synchronizely.
9.9 Arrhythmia Monitoring
9.9.1 Arrhythmia Analysis
The arrhythmia algorithm is used to monitor ECG of adult patients in clinics, and detect the
changes of heart rate and ventricular rhythm, and also save arrhythmia events and generate alarm
information. Arrhythmia algorithm can monitor paced and non-paced patients. Qualified
