ST/AR Arrhythmia Algorithm
ST/AR Arrhythmia & ST Segment Monitoring
7-5
The intended use of the ST/AR basic arrhythmia analysis algorithm is to monitor
the patient’s ECG for heart rate and ventricular arrhythmias and to produce
events/alarms simultaneously for one or more ECG leads. The arrhythmia
algorithm is effective when monitoring both paced and non-paced patients in a
clinical environment.
IntelliVue Telemetry does not have a dedicated cardiotach. Instead, the
arrhythmia cardiotach at the Information Center is used. Therefore, the ST/AR
Arrhythmia algorithm is always on for all IntelliVue Telemetry patients, and
cannot be turned off.
ST/AR provides Heart Rate and PVC Rate numerics and alarm detection for the
conditions listed in the following table. There are two detection levels: Basic and
Enhanced. Enhanced includes the Basic alarms.
