6.7.5 Initiating Arrhythmia Relearning Manually
Normally arrhythmia relearning allows the equipment to learn new ECG patterns to correct arrhythmia alarms and heart
rate value. We suggest you to manually initiate arrhythmia relearning when you suspect the result of arrhythmia
analysis.
To initiate relearning manually, select the ECG parameter window to enter the [ ECG Setup ] menu, select [ Arrhythmia
>> ] [
→
Relearn Arrh. ]. When the equipment is learning, the message “Learning ECG” is displayed in the technical alarm
area.
NOTE
z
Arrhythmia relearning in the case of ventricular tachycardia may affect correct arrhythmia alarm.
6.7.6 Automatic Arrhythmia Relearn
Arrhythmia relearning is initiated automatically whenever:
„
The ECG lead or lead label is changed
„
The ECG lead is re-connected
„
Patient category is changed
„
The paced status is changed,
„
Arrhythmia analysis is switched on
„
[ Stop Calibrating ] is selected after ECG calibration is completed.
6.8 Calibrating ECG
The ECG signal may be inaccurate due to hardware or software problems. As a result, the ECG wave amplitude becomes
greater or smaller. In that case, you can perform ECG calibration to check if the ECG wave amplitude is in normal range.
1. Select ECG filter hot key. Turn the navigation knob to select [ Diagnostic ] mode.
2. Select the ECG parameter area to enter the [ ECG Setup ] menu.
3. Select [ Others >> ] [
→
Calibrate ]. In this case, a square wave appears on the screen and the message “Calibrating
ECG” is displayed.
4. Compare the amplitude of the square wave with the 1 mV wave scale. The difference should be within 5%.
5. After the calibration is completed, select [ Stop Calibrating ].
You can print out the waveform and wave scale and then measure the difference between them if necessary. If the
difference exceeds 5%, contact your service personnel.
