To initiate a relearn of a patient's reference beats for ST-segment analysis
The relearn operation cannot be undone.
1. In the patient's Virtual Monitor, click Setup, ST Analysis.
The ST Analysis Setup window appears.
2. Carefully evaluate the patient's current ST segment for all active leads to ensure that
you want the Acuity System to establish the beat as the patient's reference beat for
ST Analysis.
3. Click ST RELEARN.
The waveform area displays NO VALID BEATS for up to 30 seconds.
The current beat for each ECG lead becomes the reference beat, and the deviation
value for each current beat becomes zero.
4. Closely examine the current ST segment for all active leads to ensure that the Acuity
System has defined an appropriate ST analysis reference beat.
