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
