ARR Alarms Occurring Condition
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
Basic:
5 consecutive ventricular beats, and ventricular HR < 40 bpm.
Advanced:
5 consecutive ventricular beats, and ventricular HR < 20 bpm.
Vent Rhythm
Basic:
5 consecutive ventricular beats, and 40 bpm ≤ ventricular HR < 100 bpm.
Advanced:
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.
Applicable to Advanced ARR:
Sustain VT
The duration of ventricular tachycardia rhythm ≥ the threshold value that has
been set.
ExtremeTach
HR ≥ Extreme Tachycardia threshold value that has been set.
ExtremeBrad
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.
Acc. Vent
Rhythm
5 consecutive ventricular beats, and 40 bpm ≤ ventricular HR < 100 bpm.
Pause
No QRS is detected within the heartbeat pause threshold value that has been
set.
Pauses/min
High
The measurement value of Pause/min is greater than high alarm limit that has
been set.
VEB
The delayed ventricular beats detected in normal heartbeats occur more than
or equal to 3 times within 30 s.
