ST/AR ST Analysis Algorithm

Intended Use

The intended use of the ST/AR ST Analysis algorithm is to monitor an adult
patient's ECG for ST segment elevation or depression and produce
events/alarms for all possible ECG leads. The ST Analysis algorithm is
capable of monitoring paced and non-paced adult patients.
Note—The ST Analysis algorithm does not analyze ventricularly paced or
ventricular ectopic beats.
Warning
This device provides ST level change information; the clinical significance
of the ST level change information needs to be determined by a physician.
The ST/AR ST algorithm at the Information Center monitors ST segment
elevation or depression for each available telemetry ECG lead and produces
events/alarms simultaneously. ST values update with every measurement
period and enunciate, depending upon the severity of the change, events
and alarms as they are detected.
The ST/AR ST algorithm is approved for use only with non-paced and
atrially-paced adult telemetry-monitored patients. With EASI monitoring,
ST analysis is performed on up to 12 leads, and an additional value of ST
index is calculated and displayed. Assessment of EASI-derived 12-lead ST
measurement is recommended for adult patients that meet the following
parameters:
All ST analysis and ST alarms for telemetry patients are performed by the
Information Center.
