ECG Monitoring

8.9 ECG Relearn
Changes in the ECG templates may lead to false arrhythmia alarm and / or inaccurate heart rate.
This Monitor provides the function of ECG Relearn, which enables the Monitor to learn new ECG templates, thus to
correct false arrhythmia alarms and inaccurate heart rate values. After the completion of ECG relearning the
Monitor saves learned QRS waveforms as templates for the patient's normal ECG waveform. During ECG monitoring
you may need to start an ECG Relearn process if you suspect that there is an abnormal arrhythmia alarm.
8.9.1 Start ECG Relearn Automatically
ECG Relearn starts automatically in the following situations:
Upon startup of the device.
Change of lead type or name.
Reconnection of lead after falling off for over 60s.
Change of the patient's pacer setup.
8.9.2 Start ECG Relearn Manually
1) Select the ECG parameter area or waveform area to enter [ECG] menu.
2) Select [Relearn] button under the [ECG] menu to start ECG Relearn.
Please start ECG Relearn during normal rhythm and when ECG signal is relatively noiseless. This is
because ECG Relearn during the arrhythmia period may result in relearning the wrong QRS complex as
the ECG template, and thus missing the arrhythmic event.
8.10 Defibrillation Synchronization
The Defibrillation Synchronization function is to output a defibrillation synchronization signal (+5V, 100ms width)
via the multi-function connector once the Monitor detects R wave. The synchronization signal is for use by the
defibrillator.
Improper use of the defibrillation function may cause injury to the patient; the user should judge
whether defibrillation is needed or not according to the patient's actual condition.
Prior to defibrillation, the user should set the filter mode to [Diagnosis]. At the end of defibrillation, the
user can select the filter mode as required.
