ST/AR Arrhythmia Algorithm
Beat classification determined by the ST/AR algorithm is shown on the primary
delayed wave in the Arrhythmia Analysis window at the Information Center. To
access this window, select Arrhythmia Analysis from the Patient Window.
The annotation requires clinical validation of the analyzed heart rhythm. If the
analysis is inaccurate, perform a relearn of the rhythm.
When monitoring is initiated, when the Primary Wave is changed, or if Relearn
is selected, a question mark (?) is displayed next to HR and the annotation "L"
appears on the annotated wave until the HR is calculated and the rhythm is
learned.
