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.
