Alarm
Definition
**QTc High
The QTc high limit alarm is a long yellow alarm that
occurs when there are two consecutive 5 minute QTc
values above the set alarm limit.
**dQTc High
The dQTc alarm is a long yellow alarm that occurs
when the difference between the current value and
the baseline value exceeds the set limit for two
consecutive 5 minute dQTc values. The dQTc alarm
has a lower priority than the QTc High alarm.
Cannot Analyze QT
When there are two consecutive invalid 5 minute
values the Information Center generates a Cannot
Analyze QT soft INOP and displays a question mark
(?) for the QT parameter value. The Information
Center displays the Cannot Analyze QT INOP
without the question mark during initial startup and
during the learning phase.
