ST Setup
Call up the ST Setup menu by clicking on the ST parameter box.
For each ST lead selected, the ST Setup menu displays the following:
z
ST Segment Waveform — Includes the last averaged QRS complex. The
label and scale of the ST waveform appear on the left side of the waveform.
The waveform scale is the same scale used for the ECG lead displayed on the
main screen.
z
Position of Isoelectric and ST Measurement Points — Allow the clinician
to display and set the isoelectric and ST measurement points in relation to the
beginning and end of the QRS complex, respectively. When you click on
or
, the location of the isoelectric and measuring points is indicated by
ST
vertical lines on the ST1 and ST2 waveforms. Numerical values at the bottom
and on the right side of the waveforms further define the location of these two
points (in milliseconds or millimeters/millivolts).
z
Ref(erence) — Displays or hides the ST reference complex, a purple
waveform obtained by saving the currently displayed ST waveform.
z
Save — Saves and time-stamps the currently displayed ST waveform as a
reference
waveform overlaps the reference waveform to show changes in the ST
segment.
