When turning ST ANALYSIS on, the monitor selects DIAGNOSTIC mode automatically.
You can set the monitor to MONITOR or SURGERY mode as required. However, ST
analysis will turn off automatically.
With the ST analysis, the variance of the ST segment at the waveform tracks of the selected
lead can be measured. The ST measurement result is displayed numerically in the ST1 and
ST2 positions in the parameter window.
You can review the ST trend graph and trend data in the TREND GRAPH and the TREND
TABLE menus.
Measurement unit of the ST segment: mV (millivolt).
Measurement symbols of the ST segment: “+” means positive elevation, “-” means negative
elevation.
Measurement range of the ST segment: -2.0 mV to +2.0 mV.
WARNING
z ST analysis is not intended for neonatal patients.
z The ST algorithm has been tested for accuracy of the ST segment data. The
significance of the ST segment changes need to be determined by a clinician.
