measurement points. The isoelectric point provides the baseline for the measurement and the

ST point provides the other measurement point.

The ST measurement points need to be adjusted when you start monitoring, and if the

patient’s heart rate or ECG morphology changes siginificantly. Artifactual ST segment

depression or elevation may occur if the ISO or the ST point is incorrectly set.

NOTE

•

Abnormal QRS complex is not considered in ST analysis.
