So you should closely monitor patient condition during and for several minutes after the learning
phase to allow the algorithm to reach optimal detection performance.
10.7.2 Arrhythmia Events
This section lists all arrhythmia events and their criteria.
10.7.2.1 Lethal Arrhythmia Events
10.7.2.2 Nonlethal Arrhythmia Events
Arrhythmia message Description
Asystole No QRS complex detected within the set time interval in the absence of ventricular
fibrillation or chaotic signal.
V-Fib/V-Tach A fibrillatory wave for 6 consecutive seconds.
A dominant rhythm of adjacent PVCs and the ventricular rate is greater than the V-tach rate
limit.
V-Tach The number of consecutive PVCs is greater than or equal to the V-Tach PVCs limit, and the
ventricular rate is greater than or equal to the V-Tach rate limit.
Vent Brady The number of consecutive PVCs is greater than or equal to V brady PVC limit and the
ventricular rate is less than the V brady rate limit.
Extreme Tachy The heart rate is greater than the extreme tachycardia limit.
Extreme Brady The heart rate is less than the extreme bradycardia limit.
Arrhythmia message Description
R on T R on T PVC is detected.
Run PVCs More than two consecutive PVCs, but lower than the V brady PVCs limit, and the ventricular
rate is lower than the V-Tach rate limit.
Couplet A Pair of PVCs detected in between normal beats.
Multiform PVC Multiform PVCs detected in Multif. PVC's Window (which is adjustable).
PVC One PVC detected in between normal beats.
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.
Tachy The heart rate is greater than the tachycardia limit.
Brady The heart rate is lower than the bradycardia limit.
Pacer Not Capture No QRS complex detected for 300 ms following a pace pulse (for paced patients only).
Pacer Not Pacing No pace pulse detected for 1.75 x average R-to-R intervals following a QRS complex (for
paced patients only).
Missed Beat At least 3 consecutive Ns, and
The current RR interval is greater than 1.5 x previous RR interval, and
The next RR interval is lower than 1.5 x average RR interval, and
HR lower than 100 and the current RR interval is greater than 1.75 x average RR interval , or
HR is greater than or equal to 100 and the current RR interval is greater than 1000 ms.
Nonsus V-Tach The number of consecutive PVCs is lower than the V-Tach PVCs limit but greater than 2, and
the ventricular rate is greater than or equal to the V-Tach Rate limit.
Vent Rhythm The number of consecutive PVCs is greater than or equal to the V Brady PVCs limit, and
ventricular rate is greater than or equal to the V Brady Rate limit but lower than V-Tach Rate
limit.
