Relearning Monitoring ECG, Arrhythmia, ST and QT
7 - 36 TM80 Telemetry Monitor Operator’s Manual
7.10.1 Automatically Initiating an ECG Relearning
Auto arrhythmia relearning is initiated in the following situation:
■ The ECG lead type or lead label is changed.
■ ECG leads are off and are not reconnected within 60 seconds.
■ The patient‘s paced status is changed.
■ The patient’s category is changed.
■ A patient is discharged.
■ After ECG calibration is completed, the Calibrate ECG option is disabled.
■ When Cable Type is set to 3 Lead, the monitored lead is changed.
7.10.2 Manually Initiating an ECG Relearning
If you suspect that false arrhythmia alarms are presented, you may need to manually ini-
tiate an ECG relearn.
To do so, follow this procedure:
1. On the main screen, tap the QT digital area to enter the QT/QTc menu.
2. Tap Relearn.
OR
1. On the main screen, tap the arrhythmia digital area to enter the
Arrhythmia
menu.
2. Tap Relearn.
OR
1. On the main screen, tap the ST digital area to enter the ST menu.
2. Tap Relearn.
CAUTION
• Initiate ECG relearning only during periods of predominantly normal
rhythm and when the ECG signal is relatively noise-free. If ECG learning
takes place during arrhythmias, the ectopic beats may be incorrectly
learned as normal QRS complexes. This may result in missed detection of
subsequent arrhythmia events.
