ST ANALYSIS
PatientNet performs ST analysis on ambulatory and bedside monitored patients as
described in this section. Arrhythmia processing and ST Analysis is not performed
when the device type is a ventilator.
Enabling ST Analysis
To enable ST analysis:
1. Press Setup on the Main screen and select the patient.
2. Set Process to ST and make further ST settings as instructed in this section.
Process can be set to ST, None or Pacer. See “Pacemaker Processing” on
page 95 for pacer information.
WARNING: While the ST algorithm has been validated for accuracy in detecting ST
changes, the clinical significance of ST changes can be determined only by a
physician.
The Central Station performs ST analysis on patients with ECG waveforms whose
alarm source is set to Central, Arrhythmia is ON and ST is enabled.
For bedside arrhythmia source patients, the Central Station does not process arrhyth-
mias, but does display and print digital ST data if the bedside device transmits it.
WARNING: For ambulatory patients connected to DT-4500 transceivers undergoing ST
analysis, program the transceiver to 0.05 Hz frequency response. Otherwise,
unpredictable and inaccurate ST analysis will result.
Viewing ST Analysis Data
ST information is shown on the ST Analysis screen. Press the View button on the
Main screen and then ST on the View screen to display the ST Analysis screen.
