Arrhythmia Relearning
During a learning phase:
• Alarm timeout periods are cleared
• Stored arrhythmia templates are cleared
• Asystole, Vfib, and HR alarms (when there are enough beats to compute the HR) are active. No
other alarms are active.
Initiating Arrhythmia Relearning Manually
To initiate relearning manually, in the Setup Arrhy menu, select Relearn Arrhy.
– While the monitor is learning, the delayed arrhythmia wave displays the beat label
L and the
rhythm status message
Learning ECG.
– Next, the monitor determines the dominant rhythm. The beats are labeled
N, and the rhythm
status message changes to
Learning Rhythm.
After relearning is complete, you should check the delayed arrhythmia wave to ensure that the
algorithm is labeling the beats correctly.
If beats are still not classified correctly, check that the ECG is optimized for arrhythmia monitoring.
You may need to select a different lead or change the electrodes or electrode positions if there is
excessive noise, unstable voltage, low amplitude, or large P- or T-waves.
Automatic Arrhythmia Relearn
Arrhythmia relearning is initiated automatically whenever:
• ECG monitoring is switched on
• The ECG Lead or Lead Label of the primary/secondary lead is changed manually, or when
fallback occurs
• A Leads Off INOP condition (that has been active for > 60 seconds) ends.
If you are monitoring multi-lead arrhythmia and there is a change in one lead only, relearning happens
only in the affected lead. During this learning phase, the system will continue monitoring using the
other lead. Therefore, the delayed arrhythmia wave is not labeled
L and there is no Learning ECG
rhythm status message. In addition, alarm timeout periods are maintained, stored arrhythmia templates
are maintained for the operative lead, and all alarms switched on are active.
Arrhythmia Relearn and Lead Fallback
Lead fallback triggers an automatic arrhythmia relearn.
WARNING
If arrhythmia 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.
For this reason you should:
• take care to initiate arrhythmia relearning only during periods of predominantly normal rhythm
and when the ECG signal is relatively noise-free
• be aware that arrhythmia relearning can happen automatically
