10.7.4 Adjust ISO/ST point
These two points can be adjusted by turning the knob.
For ST measurement points setting, enter the "DEF POINT" window. The QRS complex template displays in the
window (If the channel is switched off, the system prompts "ST ANALYSIS KEY IS OFF!".). It is adjustable of the
highlight lines in the window. You may select ISO or ST, then switch the knob left or right to move the line, then to
decide the baseline point and the measurement point.
NOTE:
l
The alarm limits for two ST measurements are identical. The setting of alarm limits can not be made only
for one channel.
10.7.5 ST alarms and Prompt messages
Among physiological alarms, those belonging to the type that the parameter has exceeded the limits may activate the
recorder to automatically output the parameters and related measured waveforms when the alarms occur on the
condition that the alarm record switch in related menu is On.
Possible physiological alarms during ST measurement are listed as below.
Physiological alarms:
Message
Cause
Alarm Level
ST1 HI
ST measuring value of channel 1 is above the upper alarm limit.
User-selectable
STI LOW
ST measuring value of channel 1 is below the lower alarm limit.
User-selectable
ST2 HI
ST measuring value of channel 2 is above the upper alarm limit.
User-selectable
ST2 LOW
ST measuring value of channel 2 is below the lower alarm limit.

10.8 ARR Monitoring
Arrhythmia analysis
The arrhythmia analysis is used to monitor ECG of neonate and adult patient in clinical, detect the changing of heart
rate and ventricular rhythm, and also save arrhythmia events and generate alarming information. Arrhythmia analysis
can monitor the patient with or without pacemaker. Qualified personnel can use arrhythmia analysis to evaluate patient’s
condition (such as heart rate, PVCs frequency, rhythm and abnormal heartbeat) and decide the treatment accordingly.
Besides detecting the changing of ECG, arrhythmia analysis can also monitor patients and give proper alarm for
arrhythmia.
n
The arrhythmia monitoring is shutoff by default. You can enable it when necessary.
n
This function can call up the doctor's attention to the patient's heart rate by measuring and classifying the
arrhythmia and abnormal heart beat, and triggering the alarm.
n
The monitor can conduct up to 13 different arrhythmia analysis.
n
The monitor can store the latest 60 alarm events (a single-channel ECG waveform 4 seconds before and after
the alarm) during the arrhythmia analysis process. The operator can edit these arrhythmia events through this
menu.
