Turn QT Analysis On/Off
How the QT Analysis Algorithm Works
Description
Turn QT analysis on by clicking in the QT
Analysis On check box. QT analysis is on
when a checkmark displays in the check box.
When the QT measurement is on, a QT status
message is displayed in the QT Setup window,
along with the current values for QT, QTc, dQTc
and QT-HR. The lead labels indicating the leads
used to calculate the baseline and current values
also appear.
Turning QT analysis off does not clear
Note—
the baseline value. This allows you to turn QT
analysis off during prolonged arrhythmias, such
as bigeminy, without losing the baseline.
