7 ECG, Arrhythmia, ST and QT Monitoring
Ectopic Status Messages
The label B or E indicates basic (B) or enhanced (E) arrhythmia capability.
Ectopic Status Message Explanation
(No message displayed)
PACER NOT CAPT
PACER NT PACING
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
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
rhythm status message Learning ECG.
– Next, the monitor determines the dominant rhythm. The beats are labeled
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.
