6 ECG, Arrhythmia, and ST Monitoring

About the ST Measurement Points

About the ST Measurement Points

The ST value for each beat complex is the vertical difference between the ISO point and the ST point, as shown in the diagram below. The isoelectric (ISO) point provides the baseline, the ST point is at the midpoint of the ST segment. The J point is where the QRS complex changes its slope; as it is a fixed distance away from the ST point, it can be useful to help you position the ST point correctly.

R-wave peak at 0 msec

J point, for example, 48 msec

P

Q

S

Isoelectric point set to -80 msec

T

Difference = ST value

ST measurement point, for example, J + 60 msec

CAUTION The ST measurement points need to be adjusted when you start monitoring, and if the patient's heart rate or ECG morphology changes significantly, as this may affect the size of the QT interval and thus the placement of the ST point. Artifactual ST segment depression or elevation may occur if the isoelectric point or the ST point is incorrectly set.

Always ensure that ST measurement points are appropriate for your patient.

Adjusting ST Measurement Points

Depending on your monitor’s configuration, the ST point can be positioned either

• relative to the J-point.

In the Adjust ST Points window, the pop-up keys ISO Point, J Point and ST Point are visible and can be adjusted.

or

• directly. by selecting a numeric value for the ST point.

In the Adjust ST Points window, you can adjust the ISO and ST point.

The ST Uses setting can only be changed in Configuration Mode.

To adjust the ST measurement points,

1In the Setup ST Analysis menu, select Adjust ST Points to open the Adjust ST Points window. Alternatively, you can use the Adjust ST Points pop-up key in the ST Baseline window.

2Select a suitable ECG lead for ST measurement, with a visible J-point and a visible P wave. Use the up and down arrow keys to scroll through the ST snippets for the other ECG leads.
