How the QT Analysis Algorithm Works
ST/AR Arrhythmia Monitoring
7-21
Set the QT Baseline
To quantify changes in the QTc value you can
set a QTc baseline. Select the Set QT Baseline
button to replace the baseline QTc value with the
current QTc value. If a baseline has not been set
the Information Center sets the baseline to the
first valid value after measuring QT for five
minutes. Setting a new baseline discards the
previous baseline.
Notes—
• Since the dQTc alarm is based on the
difference between the baseline and the
current value, setting an inappropriate new
baseline may prevent a dQTc alarm from
being generated.
• Turning QT analysis off does not clear the
baseline value. This allows you to turn QT
analysis off during prolonged arrhythmias,
such as bigeminy, without losing the
baseline.
• Discharging a patient clears the baseline.
