ST Analysis option
The Acuity System ST Analysis option analyzes the ST segment of current ECG beats
relative to the ST segment of a reference beat. Specifically, the system reports mm or mV
of deviation between the current beat’s ST-segment offset and the reference beat’s
ST-segment offset.
The system learns the reference beats when a learning or relearn function occurs. For a
listing of when learning or relearn functions occur, see
“When ST relearn occurs for a
patient” on page 75.
In the ST Analysis Setup window, you can do the following things:
• Specify analysis preferences.
• Set alarm limits.
• Set ST alarming priority level.
• Set Print on Alarm.
• View current beats and reference beats.
• View current deviation values, including alarm values.
• Initiate relearn of a patient’s reference beats for ST analysis only.
ST analysis is not performed in these circumstances:
• If Analyze Pacers is set on in the patient’s Arrhythmia Alarms Setup window.
• If the patient monitor is set in neonate mode.
• During the occurrence of arrhythmia events.
