8.6.2.2 Nonlethal Arrhythmia Events
*N: normal beat; V: ventricular beat
8.6.3 Displaying Arrhythmia Information
You can display the arrhythmia information in the numeric area. To do so, follow this procedure:
1. Access Tile Layout using either of the following ways:
◆ Select the Screen Setup quick key → select the Tile Layout tab.
◆ Select Main Menu quick key → from the Display column select Tile Layout.
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 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.
Pause No QRS complex is detected within the set pause time threshold.
Irr Rhythm Consistently irregular rhythm (N
*, irregular RR interval change is greater than 12.5%)
A-Fib (for adult only) P wave is absent and normal beat RR intervals are irregular.
PVCs/min PVCs/min exceeds high limit.
Pauses/min Pauses/min exceeds high limit.
Irr Rhythm End Irregular rhythm no longer detected for the irregular rhythm end delay time.
A-Fib End (for adult only) Atrial fibrillation no longer detected for the A-Fib end delay time.
