relearn. An Arrhythmia Analysis function that causes the Acuity system to relearn a
patient’s normal ECG rhythm. The Acuity System uses the relearned rhythm as a
guideline to identify arrhythmia events (arrhythmia relearn) and to analyze deviation of
the ECG ST-segment offset (ST relearn).
guideline to identify arrhythmia events (arrhythmia relearn) and to analyze deviation of
the ECG ST-segment offset (ST relearn).
When relearn occurs for a patient
Both arrhythmia and ST relearn events occur after these things:
•
ST/Arr Relearn is clicked in the Arrhythmia Alarms Setup window.
•
Single ECG is clicked in the Arrhythmia Alarms Setup window
•
Patient connection, some lead changes or lead failures, system restart
Only an arrhythmia relearn event occurs after these things:
•
RELEARN is clicked in the Arrhythmia Alarms Setup window. A RELEARN button
(instead of an ST/Arr Relearn button) indicates that the system does not include
the ST Analysis option.

What occurs in a patient’s windows during and after a relearn event
•
Virtual Monitor and Waveform Window: In all instances except clicking ST
RELEARN, a visual RELEARN alert occurs. HR is taken from the patient monitor
instead of from the arrhythmia software, and real-time waveforms display as
usual.

WARNING Minimize patient movement during a RELEARN, as movement
creates noise during the reading. If the system learns an abnormal rhythm or
learns a rhythm during noise, it designates the learned rhythm as normal.
Thereafter, rhythms of this type might not trigger an alarm. Ensure that the
patient remains still for 5 minutes after the RELEARN before allowing them to
move.
