DEF POINT
The ST and ISO measurement points need to be adjusted when you start monitoring, and if the
patient's heart rate or ECG morphology changes significantly. Always ensure that ST
measurement points are appropriate for your patient. Abnormal QRS complex is not considered
in ST segment analysis.
8.10.5 Adjusting ST and ISO Measurement Points
Depending on your monitor’s configuration, the ST point can be positioned, too.
These two points can be adjusted by turning the knob. When adjusting ST measurement point, the
system will show the ST Measurement Point Window. The system displays the QRS complex
template in the window. It is adjustable for the highlight bar in the window. You may select ISO
or ST, switch the knob left or right to move the cursor line. When the cursor is at the required
position, you may select the base point or the measurement point.
8.11 Arr. Monitoring
8.11.1 Arrhythmia Analysis
The arrhythmia algorithm is used to monitor ECG of neonatal and adult patients in clinics, and
detect the changes of heart rate and ventricular rhythm, and also save arrhythmia events and
generate alarming information. 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.
The monitor can support up to 16 different arrhythmia analyses.
ARR Types
Occurring Condition
ASYSTOLE
No QRS is detected for 4 seconds
VFIB/VTAC
Ventricular tachycardia: The fibrillation wave lasts for 4
consecutive seconds; or the number of continuous Vent beats is
larger than the upper limit of cluster Vent beats (>5).
The RR interval is less than 600ms.
