Arrhythmia Monitoring Modes
Label Event Description
OFF: The monitor detects these events when Arrhythmia = OFF (via ECG)
ASY Asystole 4 seconds pass without the detection of a
valid QRS complex
VF Ventricular
Fibrillation
The monitor identifies a sinusoidal waveform
with fibrillation characteristics
Basic: The monitor detects these additional events when Arrhythmia = Basic
VT Ventricular
Tachycardia
N* or more consecutive PVCs with a beat-to-
beat rate >= the VT rate
BRDY** Sinus
Bradycardia
8 or more consecutive normal beats with an
average rate <= the BRDY rate
Full: The monitor detects these additional events when Arrhythmia = Full
RUN Ventricular
Run
3 to N-1* consecutive PVCs with a beat-to-
beat rate >= the VT rate
AIVR Accelerated Idioventric-
ular Rhythm
3 or more PVCs with a rate < the VT rate
SVT Supraventricular Tachy-
cardia
N* or more consecutive normal beats with a
beat-to-beat rate >= the SVT rate
CPT Ventricular
Couplet
A sequence of beats with the pattern: nor-
mal, PVC, PVC, normal
BGM Ventricular
Bigeminy
A sequence of beats with the pattern: nor-
mal, PVC, normal, PVC, normal
TACH Sinus
Tachycardia
N* or more consecutive normal beats with a
beat-to-beat rate >= the TACH rate
PAUS Pause A sequence of two normal beats with an N-
N* interval > the Pause rate times the aver-
age N-N interval (±100ms)
ARTF Artifact A sinusoidal signal with a frequency of 10 to
20 Hz and an amplitude > 0.4 mV p-p, or with
a frequency of 0.25 to 10 Hz and an ampli-
tude > 10 mV p-p
* N is the event count set on the Arrhythmia Setup Table.
** In neonatal mode, you can set alarm limits for BRDY in the Alarm Limits table
and the monitor alarms upon a limit violation for this event.
