Chapter 7: ST Monitoring
As shown above, the DEFAULT POINT WINDOW shows the dominant QRS complex template.
Two vertical lines indicate the positions of the ISO and ST points.
ISO: It is the base point, used to indicate the baseline point of the ST analysis. The default is
80ms.
ST: It is the ST measurement point. The default is 110ms.
(Selectable between 5 to 400 ms by step of 5ms)
The reference point is the position where the peak of R-wave locates.
NOTE:
It is good clinical practice to check the position of ISO and ST measuring points
before starting ST monitoring and finishing learning procedure.
NOTE:
In practice, the accurate determination of ISO and ST measuring points requires
careful clinical evaluation.
NOTE:
The ST measurement point should be adjusted if patient's HR or ECG morphology
changes significantly.
If the template is not established, a horizontal line will be displayed and if the ST ANALYSIS is
"OFF", the message "ST ANALYSIS KEY IS OFF" appears in this window.
You may select ISO or ST, and then switch the knob left or right to move the cursor line. When
the cursor is at the intended position, you may select the base point or the measurement point.
NOTE:
Abnormal QRS complex is not considered in ST segment analysis.
