ARR Alarms
Occurring Condition
Asystole
No QRS is detected for 4 consecutive seconds.
V-Fib/V-Tach
4 consecutive seconds' fibrillation wave occurs; Or 5 consecutive
ventricular beats, and ventricular HR ≥100 bpm.
Run PVCs
3 ≤ the number of consecutive PVCs < 5
Couplet
2 consecutive PVCs
PVC Bigeminy
A dominant rhythm of N, V, N, V (N = supraventricular beat, V =
ventricular beat) was detected.
PVC Trigeminy
A dominant rhythm of N, N, V, N, N, V
R on T
A type of single PVC under the condition that HR < 100, R-R interval is
less than 1/3 the average interval, followed by a compensating pause of
1.25X the average R-R interval (the next R wave advances onto the
previous T wave).
PVC
Single PVC detected in normal heartbeats, and the number of consecutive
single PVC ≥ 4 within 30 s.
Tachy
Adult: RR interval for 5 consecutive QRS complex ≤ 0.5 s.
Pediatric/neonatal: RR interval for 5 consecutive QRS complex ≤ 0.375 s.
Brady
Adult: RR interval for 5 consecutive QRS complex ≥ 1.5 s.
Pediatric/neonatal: RR interval for 5 consecutive QRS complex ≥ 1 s.
Missed Beat
If HR < 120 bpm, no beats are detected for 1.75 times average RR
interval; or if HR ≥ 120 bpm, no beats are detected for one second;
Irr Rhythm
Consistently irregular heart rhythm
Pacer not
Capture
No QRS complex detected in 300 ms after a pace pulse.
Pacer not
Pacing
No pace pulse detected in 1.75 times RR interval after a QRS complex.
Vent Brady
5 consecutive ventricular beats, and ventricular HR < 20 bpm.
Vent Rhythm
5 consecutive ventricular beats, and 20 bpm ≤ ventricular HR < 40 bpm.
PVCs High
The measurement value of PVCs is greater than high alarm limit that has
been set.
Sustain VT
The duration of ventricular tachycardia rhythm ≥ the threshold value that
has been set.
ExtremeTachy
HR ≥ Extreme Tachycardia threshold value that has been set.
ExtremeBrady
HR ≤ Extreme Bradycardia threshold value that has been set.
V-Tach
5 consecutive ventricular beats and ventricular HR ≥ 100 bpm.
Wide QRS
Tachy
Meet tachycardia conditions, and QRS wave width ≥ 160 ms.
Non-Sustain
VT
3 ≤ The number of consecutive ventricular beats < 5, and ventricular HR
≥ 100 bpm.
Afib
Atrial fibrillation alarm should meet below two conditions for 1 minute:
The RR interval of normal beats must be irregular, and it can be seen that
the obvious f or P waves do not exist.
