Lethal and Non-lethal arrhythmia alarms and events may occur at the Panorama Central
Station.
6.4.1 Lethal Arrhythmia Alarms
A lethal arrhythmia is an arrhythmia that can be life threatening to a patient if left untreated.
Ventricular Tachycardia (V-Tach), Ventricular Fibrillation (V-Fib) and Asystole alarms are lethal
arrhythmias.
Ventricular Tachycardia (V-Tach) Alarm
A V-Tach alarm is defined as follows:
When using a 3-wire or 5-wire lead set, the V-Tach lethal arrhythmia alarm is activated
when there are eight or more consecutive PVCs at a rate equal to or greater than the
configured V-Tach threshold.
When using a 12 lead card, the V-Tach lethal arrhythmia alarm is activated when the
user configurable number of consecutive PVCs is reached at a rate equal to or greater
than the V-Tach threshold.
NOTE: A V-Tach alarm is a latched alarm that must be
acknowledged after the condition resolves.
NOTE: The V-Tach alarm is not available for the Neonate patient
size.
A V-Tach alarm is a Priority 1 alarm event that behaves as follows:
The V-Tach alarm produces the Alarm Priority 1 visual and audio alarm indicators once
the condition is identified.
The V-Tach alarm shows a V-Tach alarm message in red text in the Patient Status line.
The V-Tach arrhythmia alarm is associated with Alarm Priority 1 audio sound.
For additional information, refer to ‘‘Alarm Behavior’’ on page 3-1.

for four consecutive seconds.

acknowledged after the condition resolves.
NOTE: The V-Fib alarm is not available for the Neonate patient
size.
The V-Fib alarm is a Priority 1 alarm event that behaves as follows:
The V-Fib alarm produces Alarm Priority 1 visual and audio alarm indicators once the
condition is identified.
