8.10 ECG Relearning
8.10.1 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 patient
monitor is learning, the message [ECG Learning] is displayed in the technical alarm area.
CAUTION
z 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.
8.10.2 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 the calibration is completed, select [Stop Calibrating ECG]
A switch happens between the options of screen type during 5/12-lead ECG monitoring.
The paced status of the patient is changed.
