None of the signal amplitudes of I, II and III leads
exceeds that of the alarm threshold that has been set.
PS: this alarm is available for 5 or 12 leads only, not
available for 3 leads.
PVCs measuring value is above the upper alarm limit.
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
2 consecutive PVCs
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 <
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).
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
detected for one second.
Consistently irregular heart rhythm
PACER NOT CAPTURE: no QRS complex detected
in 300ms after a pace pulse.
120 bpm, no beats are
