7.7.3 Changing Arrhythmia Alarm Settings
To change arrhythmia alarm settings, follow this procedure:
1. On the main screen, tap the HR digital area or ECG waveform area to enter the ECG
menu.
2. In the Parameter Setup section, tap Arrhythmia.
3. Tap Arrhythmia Alarm Setup. The Arrhythmia Alarm Setup menu is displayed.
4. In the Setup section, select the desired option:
ǂ All OnὉswitches on all arrhythmia alarms.
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%)
A-Fib 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 Atrial fibrillation no longer detected for the A-Fib end delay time.
