7.9.2.2 Nonlethal Arrhythmia Events
Arrhythmia message Description
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.
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 Beats 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.
Pause No QRS complex is detected within the set time threshold of pause.
Irr Rhythm Consistently irregular rhythm (N, irregular RR interval change is
greater than 12.5%)
