8.7 About Arrhythmia Monitoring
Arrhythmia analysis provides information about your patient’s condition, including heart rate, PVC rate, rhythm and
ectopics.
WARNING

The arrhythmia analysis program is intended to detect ventricular arrhythmias. It is not designed to detect
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.
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 PVCs/min exceeds high limit
Nonlethal
arrhythmia
Pacer not paced
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 milliseconds following a pace pulse (for paced
patients only).
PVC One PVC detected in normal heartbeats.
Couplet Paired PVCs detected in normal heartbeats.
VT > 2 More than 2 consecutive PVCs.
Bigeminy A dominant rhythm of N, V, N, V, N, V.
Trigeminy A dominant rhythm of N, N, V,N, N, V, N, N, V.
R on T R on T detected in normal heartbeats.
Missed Beats
No beat detected for 1.75 x average R-R interval for HR <120, or
No beat for 1 second with HR > 120 (for non-paced patients only), or
No beat detected for more than the set pause threshold.
Brady The average heart rate is equal to or less than the bradycardia limit.
Tachy The average heart rate is equal to or greater than the tachycardia limit.
Vent. Rhythm
The consecutive PVCs ≥ the Vbrd PVCs limit, and the HR ≥ Vbrd Rate limit but <
the Vtac Rate limit.
Multif. PVC Multiform PVCs detected in Multif. PVC's Window (which is adjustable).
Nonsus. Vtac The consecutive PVCs < the Vtac PVCs limit but > 2, and HR ≥ the Vtac Rate limit.
Pause No QRS detected within the set time threshold of pause.
Irr. Rhythm Consistently irregular rhythm.
