ST Measuring Points
You can change the ST measuring points and
isoelectric point from the general or from the single
ST-complexes page (see illustrations on
page 164). In both pages, the setup buttons for
changing the measuring points are located at the
bottom of the screen. Changing the measuring
point of one complex adjusts the measuring points
for all ST complexes.
Adjusting ST Measuring Points
Whenever you adjust the isoelectric and ST
measuring points, the ST deviation is recomputed.
During this computation, the changing ST-deviation
values appear yellow. The values appear green
when the computation is completed.
To change the ST measuring points
1 Select the HR parameter box to select the ECG
setup page directly
or
Select Sensor parameters... from the main-
menu bar > ECG tab to access the ECG setup
page.
2 Select the ST complex tab (C) to display the
general ST-complexes page.
3 Select an individual ST panel to zoom in on a
single ST complex.
4 Select the ISO button (I) and use the rotary
knob to dial to the desired setting.
5 Select the ST button (G) and use the rotary
knob to adjust the ST measuring.
ST Reference
You can save the ST reference complexes as
reference points for future ST deviation
measurement comparisons. The first time you
relearn the QRS complexes, the current ST data
are saved as reference data. The original ST
reference data are updated each time you save the
ST references.
Saving ST Reference Points
You can save the ST reference from the general
ST-complexes page (see page 164) and the single
ST-complex page (see page 163). Saving a
reference point in either screen, saves all currently
displayed ST complexes as reference points.
To save the ST reference points
1 Select the HR parameter box to select the ECG
setup page directly
or
Select Sensor parameters... from the main-
menu bar > ECG tab to access the ECG setup
page.
2 Select the ST complex tab to display the
general ST-complexes page.
3 Select an individual ST panel to zoom in on a
single ST complex.
4 Select the Save reference button (in either ST
complex page) and use the rotary knob to dial
to the desired setting.
