Directions for use
Initiate a relearn of a patient's reference beats for ST analysis
Description of the Relearn function
Arrhythmia and ST relearn is 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).
If you want to establish a new ST reference beat without changing the normal ECG
rhythm used for arrhythmia analysis, initiate relearn in the ST Analysis Setup window.
When ST relearn occurs for a patient
• Only ST reference beat learning occurs when ST RELEARN is clicked in the ST
Analysis Setup window.
• ST relearn also occurs along with Arrhythmia relearn when certain buttons are clicked
in the Arrhythmia Alarms Setup window. For details, see
ECG rhythm"
What occurs in a patient's windows during and after ST RELEARN is clicked
• ST Analysis Setup window: The waveform slice displays NO VALID BEATS, and the
Acuity System can take up to 30 seconds to update the waveform.
• Most review windows and some printouts: Relearn and Learning Done event markers
(▼) appear.
