- 75 -
The monitor can support up to 16 different arrhythmia analyses.
ARR Types Occurring Condition
ASYSTOLE
No QRS is detected for 4 consecutive seconds
VFIB/VTAC
Ventricular tachycardia: The RR interval of 4-second fibrillation
wave or 5 consecutive ventricular beats is less than 600 ms.
VT>2
3< the number of cluster PVCs < 5
COUPLET
2 consecutive PVCs
BIGEMINY
Vent Bigeminy
TRIGEMINY
Vent Trigeminy
R ON T
A type of single PVC under the condition that HR<100ˈR-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.
TACHY
Adult: 5 consecutive QRS complex, RR interval <
0.5s (HR
range: 120~300bpm).
Pediatric/neonatal: 5 consecutive QRS complex, RR interval <
0.375s (HR range: 160~350bpm).
BRADY
Adult: 5 consecutive QRS complex, RR interval  1.5s (HR
range: 15~40bpm).
Pediatric/neonatal: 5 consecutive QRS complex, RR interval 
1s (HR range: 15~60bpm).
MISSED
BEATS
When HR is less than 120 beats/min., no heart beat is tested
during the period 1.75 times of the average RR interval; or
When HR is  120 beats/min, no beat is tested within 1 second.
IRR
IRREGULAR RHYTHM: The patient has irregular heart rate.
PNC
PACE NOT CAPTURE: After the pacemaker is paced, QRS
complex can not be detected during 300ms.
PNP
PACER NOT PACED: After the QRS complex, no pace is
detected during 1.75 times of RR interval.
VBRADY
VENTRICULAR BRADYCARDIA: The interval of 5
consecutive ventricular wave is more than 1000 ms.
VENT
VENTRICULAR RHYTHM: The interval of 5 consecutive
ventricular wave ranges from 600 ms to 1000 ms.
