WARNING
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.
8.6.1
Switching ST On and Off
To switch ST monitoring on or off:
1. In the [
ECG Setup
] menu, select [
ST Analysis >>
].
2. Select [
ST Analysis
] to toggle between [
On
] and [
Off
].
Reliable ST monitoring can hardly be ensured if:
You are unable to get a lead that is not noisy.
Arrhythmias such as atrial fib/flutter cause irregular baseline.
The patient is continuously ventricularly paced.
The patient has left bundle branch block.
In these cases, you may consider switching ST monitoring off.
8.6.2
Changing ST Filter Settings
ST segment analysis can be carried out only when the filter mode is set to [
Diagnostic
] or [
ST
]. When ST segment
analysis is switched on, [
Filter
] will automatically switch to [
ST
] if it is not [
Diagnostic
] or [
ST
]. When ST segment analysis
is switched off, the filter mode automatically switches to the previous manual setting.
However, if you switch [
Filter
] to [
Monitor
] or [
Surgery
], ST segment analysis will turn off automatically. In case that you
change [
Monitor
] or [
Surgery
] to [
Diagnostic
] or [
ST
], ST segment analysis keeps off, you can turn it on manually.
NOTE
When the filter mode is switched to [Diagnostic], the notch filter automatically switches to [Off]. In this case,
you can still set the notch filter to [On] manually.
When the filter mode is [Monitor], [Surgery] or [ST], the notch filter is fixed to [On], and can not be changed.
8.6.3
Understanding the ST Display
8.6.3.1
ST Segment
ST segment shows a QRS complex segment for each measured ST lead. The current ST segment is drawn in the same
color as the ECG wave, usually green, superimposed over the stored reference segment, drawn in a different color. The
information is updated once every ten seconds.
To display the ST segment on normal screen:
1. Enter the [
ST Analysis
] menu. Set [
ST Analysis
] to [
On
].
2. Enter the [
Screen Setup
] window of the [
Screens
] menu. Set [
ST Segment
] to be displayed.
