7 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.
Arrhythmia Alarms and Latching
When using arrhythmia analysis, Visual Latching and Audible Latching should be on
for red alarms, or at least Visual Latching should be on. Because of the transient nature of
arrhythmia alarms, many arrhythmia conditions may go unnoticed if alarm latching is off. This setting
can only be changed in Configuration Mode.
Switching Individual Arrhythmia Alarms On and Off
Some arrhythmia alarms can be individually switched on or off. They are:
Pacer not capture, Pacer not pace, Non-Sustain VT, Vent Rhythm, Run PVCs, Pair PVCs, R-on-T
PVCs, V.Bigeminy, V.Trigeminy, Multif.PVCs, Pause, SVT, Irregular HR, Missed Beat, PVCs/min
To switch individual alarms on or off, in the Setup Arrhythmia menu, select the alarm from
the list to toggle between On and Off. The monitor displays the INOP message SOME ECG
ALRMS OFF, if configured, when more alarms are switched off than configured in your active
Switching All Yellow Arrhythmia Alarms On or Off
All yellow arrhythmia alarms can be switched on and off together. To do this,
In the Setup Arrhythmia menu, select All Yellow Off or All Yellow On.
Adjusting the Arrhythmia Alarm Limits
Some arrhythmia alarms have limits which can be individually adjusted. They are:
Vtach HR, Vtach Run, PVCs/min, Vent Rhythm, SVT HR, SVT Run, Asystole Thresh., Pause
To adjust alarm limits, in the Setup Arrhythmia menu, select the alarm to be adjusted.
Select the appropriate setting from the pop-up list.
