Telemetry Transmitter User Manual Monitoring ECG
DEF POINT
About ISO and ST measurement points:
For telemetry transmitters, the location of ISO and ST measurement points is not adjustable. Its
initial value for ST testing points is
+84ms by default. ST analysis takes no account of abnormal
QRS wave.
15.16 Arr. Monitoring
15.16.1 Arrhythmia Analysis
The arrhythmia algorithm is used to monitor ECG of adult patients in clinics, and detect the
changes of heart rate and ventricular rhythm, and also save arrhythmia events and generate
alarming information. The arrhythmia analysis is not clinically validated for use with neonatal
and pediatric patients. Arrhythmia algorithm can monitor paced and non-paced patients. Qualified
personnel can use arrhythmia analysis to evaluate patient’s condition (such as heart rate, PVCs
frequency, rhythm and ectopic beat) and decide the treatment. Besides detecting change of ECG,
arrhythmia algorithm can also monitor patients and give proper alarm for arrhythmia.
Telemetry transmitter can support up to 16 different arrhythmia analyses.
ARR Types
Occurring Condition
ASYSTOLE
No QRS is detected for 4 consecutive seconds
VFIB/VTAC
4 consecutive seconds' fibrillation wave occurs, or each RR interval for 5
consecutive ventricular beats is less than 600 ms.
VT>2
3 ≤ the number of consecutive PVCs < 5
COUPLET
2 consecutive PVCs
BIGEMINY
A dominant rhythm of N, V, N, V (N = supraventricular beat, V =
ventricular beat) was detected.
TRIGEMINY
A dominant rhythm of N, N, V, N, N,V.
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).
