5.1 Physiological Alarm Information
Message Cause Alarm level
ECG Too Weak Can not detect the signal in designated time period. High
ST-X High
ST measuring value is above the upper alarm limit. (X
stands for I, II, III, aVR, aVL, aVF, V, V1, V2, V3, V4,
V5 or V6)
User-selectable
ST-X Low
ST measuring value is below the lower alarm limit.(X
stands for I, II, III, aVR, aVL, aVF, V, V1, V2, V3, V4,
V5 or V6)
User-selectable
ASYSTOLE No QRS is detected for 4 consecutive seconds User-selectable
VFIB/VTAC
Ventricular tachycardia: The fibrillation wave lasts for
4 consecutive seconds; or the n
umber of continuous
Vent beats is larger than the upper limit of cluster Vent
beats (>
5). The RR interval is less than 600ms.
User-selectable
VT>2 3< the number of cluster PVCs < 5 User-selectable
COUPLET 2 consecutive PVCs User-selectable
BIGEMINY Vent Bigeminy User-selectable
TRIGEMINY Vent Trigeminy User-selectable
R ON T
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).
User-selectable
PVC
Single PVCs
not belonging to the type of above
mentioned PVCs.
User-selectable
TACHY
5 consecutive QRS complex, RR interval is less than
0.5s.
User-selectable
BRADY
5 consecutive QRS complex, RR interval is longer than
1.5s.
User-selectable
MISSED BEATS
When HR is less than 100 beats/min., no heart beat is
tested during the period 1.75 times of the average RR
interval; or
When HR is higher than 100 beat/min, no beat is tested
within 1 second.
User-selectable
IRR
IRREGULAR RHYTHM: The patient has irregular
heart rate, check patient’s condition, electrodes, cables
and leads.
