8.7 About Arrhythmia Monitoring
Arrhythmia analysis provides information about your patient’s condition, including heart rate,
PVC rate, rhythm and ectopics.
WARNING
z
Arrhythmia analysis program is intended to detect ventriculararrhymias and atrial
fibrillation. It is not designed to detect all the atrial or supraventricular
arrhythmias. It may incorrectly identify the presence or absence of an arrhythmia.
Therefore, a physician must analyze the arrhythmia information with other clinical
findings.
z
Atrial fibrillation (Afib) detection function is not intended for pediatric and
neonatal patients.
z
Heart-rate reading may be affected by cardiac arrhythmias. Do not rely entirely on
heart rate alarms when monitoring patients with arrhythmia. Always keep these
patients under close surveillance.
8.7.1 Understanding the Arrhythmia Events
Arrhythmia message Description Category
Asystole
No QRS detected within the set time threshold in
absence of ventricular fibrillation or chaotic signal.
Lethal
arrhythmia
VFib/VTac
A fibrillatory wave for 6 consecutive seconds.
A dominant rhythm of adjacent Vs and a HR > the
V-Tac HR limit.
Vtac
The consecutive PVCs Vtac PVCs limit, and the HR
the Vtac rate limit.
Vent. Brady
The consecutive PVCs the Vbrd threshold and the
ventricular HR < the Vbrd Rate threshold.
Extreme Tachy
The heart rate is equal to or greater than the extreme
tachycardia limit.
Extreme Brady
The heart rate is equal to or less than the extreme
bradycardia limit.
PVCs/min PVCs/min exceeds high limit
Nonlethal
arrhythmia
Pacer Not Pacing
No pace pulse detected for 1.75 x average R-to-R
intervals following a QRS complex (for paced patients
only).
Pacer Not Capture
No QRS complex detected for 300 ms following a pace
pulse (for paced patients only).
