9.9.2.4 ARR Selflearning
Pick this item ARR Selflearn to start a learning procedure, and ECG ARR Learning displayed
on the screen.
The ARR selflearning will start automatically in the following status:
 Switching the ARR Analysis from Off to On;
 Changing patient type or electrodes type;
 Connecting or switching calculation leads;
 Changing pacemaker status;
 Exiting DEMO or Standby mode;
 Admitting a patient;
 Switching calibration mode into normal measurement mode;
NOTE:
1 During the relearning phase of the algorithm, arrhythmia detection may not be
available. So you should closely monitor the patient condition during and for several
minutes after the learning phase to allow the algorithm to reach optimal detection
performance.
2 Take care to initiate ARR selflearning only during periods of predominantly normal
rhythm and when ECG signal is relatively noise-free. If ARR selflearning takes place
during arrhythmia, the ectopics may be incorrectly learned as normal QRS complex.
This may result in missed detection of subsequent events of arrhythmia.
3 If ARR selflearning is performed during ventricular rhythm, ventricular heartbeats
may be erroneously identified as normal QRS complexes. This may lead to missed
ventricular tachycardia and ventricular fibrillation events.
Due to this reason, you should:
