CAUTION

Set [Extended Arrh.] to [Disable] when the monitor is connected to the Central Monitoring System of version
prior to 06.01.00. Failure to do so may cause the Central Monitoring System to be unable to display
extended arrhythmia related alarms normally when extended arrhythmia occurs.

Please refer to the
Review

8.8 ECG Relearning
8.8.1 Initiating an ECG Relearning Manually
During ECG monitoring, you may need to initiate an ECG relearning when the patient’s ECG template changes
dramatically. A change in the ECG template could result in:
 incorrect arrhythmia alarms
 loss of ST measurement, and/or
 inaccurate heart rate
ECG relearning allows the monitor to learn the new ECG template so as to correct arrhythmia alarms and HR value, and
restore ST measurements. To initiate relearning manually, select the ECG parameter window or waveform area
→
[ Relearn ]. When the monitor is learning, the message [ ECG Learning ] is displayed in the technical alarm area.
CAUTION

Take care to initiate ECG relearning only during periods of normal rhythm and when the ECG signal is
relatively noise-free. If ECG learning takes place during ventricular rhythm, the ectopics may be incorrectly
learned as the normal QRS complex. This may result in missed detection of subsequent events of V-Tach and
V-Fib.
8.8.2 Automatic ECG Relearning
ECG relearning is initiated automatically whenever:

The ECG lead or lead label is changed

The ECG lead is re-connected

A new patient is admitted

After ECG calibration is completed and the ECG module switches to normal measurement mode by selecting [ Stop
Calibrating ECG
]

A switch happens between the options of screen type during 5-lead ECG monitoring.
 The paced status of the patient is changed.
