5 ECG, Arrhythmia, ST and QT Monitoring
Yellow Arrhythmia Alarms
Yellow arrhythmia alarms are short yellow alarms specific to arrhythmia-related patient conditions.
Depending on your monitor and Information Center configuration, they may be shown with one or
two stars. The heart rate alarms (High HR and Low HR) can be configured as short yellow or standard
yellow alarms. When they are standard yellow alarms they exist independently of the other arrhythmia
alarms and no timeout periods apply.
When arrhythmia analysis is on, all yellow ECG and arrhythmia alarms are short yellow alarms (one-
star). This means that the yellow alarm lamp and the tones are active for six seconds only, after which
the blinking numeric and the alarm message remain for up to three minutes. The only exception to this
are the HR High and Low alarms which can be configured as standard yellow alarms. Red alarms
behave as usual.
