Updating ST Baseline Snippets

ST Snippets ST snippets show a one second wave segment for each measured ST lead. The most
recent snippet is drawn in the same color as the ECG wave, usually green, superimposed over the
stored baseline snippet, drawn in a different color. The comparison shows any deviation in the
measurement since the baseline snippet was stored, for example as a result of a procedure carried out on
the patient.
The information is updated once per minute.
You can see ST snippets in the Adjust ST Points window or the ST Baseline window.
ST Baseline Window The ST Baseline Window shows an ST snippet drawn on a grid. The current
ST numeric and the ST numeric stored with the baseline are shown, as well as the difference between
these two numerics.
A "?" in front of the difference numeric indicates that the ST measurement points were adjusted since
the baseline snippet was stored.
To view the ST Baseline window, select the ST numerics, then ST Baseline.

admitted. To update ST baselines,
