pop-up key to scroll through the points and activate the point you need to

1 ST label and the ST numeric that would apply using the current points
2 1mV calibration bar
3 Cursors for adjusting ST points
4 Timestamp of most recent ST point adjustment
5 Highlighted ST point
The ISO-point cursor (1) positions the isoelectric point relative to the R-wave peak. The relation is
shown beside the ISO-point in milliseconds. Position the ISO-point in the middle of the flattest
part of the baseline (between the P and Q waves or in front of the P wave).
The J-point cursor (2) positions the J-point relative to the R-wave peak. It helps you to correctly
position the ST-point. Position the J-point at the end of the QRS complex and the beginning of
the ST segment.
The J-point cursor is not available if your monitor is configured to let you set the ST point directly.
