- 49 -
Message Cause Alarm Level
Wide QRS
Tachy
Meet tachycardia conditions, and QRS wave width ≥
160 ms.
User-selectable
Non-Sustain VT
3 ≤ The number of consecutive ventricular beats < 5,
and ventricular HR ≥ 100 bpm.
User-selectable
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.
User-selectable
Acc. Vent
Rhythm
5 consecutive ventricular beats, and 40 bpm ≤
ventricular HR < 100 bpm.
User-selectable
Pause
No QRS is detected within the heartbeat pause
threshold value that has been set.
User-selectable
Pauses/min High
The measurement value of Pause/min is greater than
high alarm limit that has been set.
User-selectable
PVCs High
The measurement value of PVCs is greater than high
alarm limit that has been set.
User-selectable
VEB
The delayed ventricular beats detected in normal
heartbeats occur more than or equal to 3 times within
30 s.
User-selectable
Multiform PVCs
Different forms of ventricular premature beats are
detected in 15 beats.
User-selectable
IPVC
The single ventricular premature beat between 2 sinus
beats with normal interval occurs more than or equal
to 3 times within 30 s.
User-selectable
PAC Bigeminy
The dominant rhythm of N, A, N, A, N, A, and the
rhythm number exceeds the number of threshold value
that has been set (N = supraventricular beat, A = atrial
beat).
User-selectable
PAC Trigeminy
The dominant rhythm of N, N, A, N, N, A, N, N, A,
and the rhythm number exceeds the number of
threshold value that has been set.
User-selectable
Low Voltage
(Limb)
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.
User-selectable
RESP APNEA
RESP can not be measured within the set apnea alarm
delay time.
