7.6 Arrhythmia Analysis
Arrhythmia analysis provides information about your patient’s condition, including heart rate and arrhythmia alarms.
In the process of ECG monitoring, if any arrhythmia event is detected, corresponding arrhythmia alarms are reported
according to the alarm level.
NOTE

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.
7.6.1 Understanding the Arrhythmia Events
Arrhythmia event Description Category
Asystole No QRS complex for 4 consecutive seconds (in absence of ventricular fibrillation
or chaotic signals).
Lethal
arrhythmia
Shockable rhythum A fibrillatory wave for 4 consecutive seconds.
A dominant rhythm of adjacent Vs and a HR > the V-Tach Heart Rate 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
PNP No pace pulse detected for 1.75 x average R-to-R intervals following a QRS
complex (for paced patients only).
PNC 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 are detected.
VT>2 More than 2 consecutive PVCs within the last minute.
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.
Brady The average heart rate is equal to or less than 60 bpm.
Tachy The average heart rate is equal to or greater than 100 bpm.
Vent. Rhythm The consecutive PVCs ≥ the Vbrd PVCs limit, and the HR is ≥ Vbrd Rate limit but
< the Vtac Rate limit.
Multif. PVC Multiform PVCs detected in Multif. PVC's Window (which is adjustable).
