ARR physiological alarms:
No QRS is detected for 4 consecutive
seconds
4 consecutive seconds' fibrillation wave
occurs, or each RR interval for 5
consecutive ventricular beats is less than
600 ms.
3< the number of consecutive PVCs < 5
A dominant rhythm of N, V, N, V (N =
supraventricular beat, V = ventricular
beat) was detected.
A dominant rhythm of N, N, V, N, N,V
A type of single PVC under the condition
that HR<100bpm, 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).
Single PVC detected in normal
heartbeats.
Adult: RR interval for 5 consecutive QRS
complex ≤ 0.5 s.
Pediatric/neonatal: RR interval for 5
consecutive QRS complex ≤ 0.375 s.
Adult: RR interval for 5 consecutive QRS
complex ≥ 1.5 s.
Pediatric/neonatal: RR interval for 5
consecutive QRS complex ≥ 1 s.
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.
