Chapter 5: ECG Monitoring
The above results are for lead II as reference lead.
- When HR High (for instance when HR reaches to 120 bpm) happens, the alarm is activated in 6
seconds. (by setting HR alarm limits between 60 bpm and 100 bpm).
- In case of cardiac Asystol, the alarm is activated in 10 seconds (from 80 bpm to 0 bpm).
- The ECG module is able to reject TALL-T pulses greater than 1.2 mv.
- Heart rates measured for the 4 irregular rhythms according to IEC 60601-2-27:2011 are as
follow:
Irregular rhythm
3a ventricular bigeminy
3b slow alternating ventricular bigeminy
3c rapid alternating ventricular bigeminy
3d bidirectional systoles

HR SOURCE
The heart rate may be derived from "ECG", "SpO2", "IBP1", "IBP2", "IBP3" and "IBP4"
signals. Default setting for this item is AUTO.
In AUTO mode the below conditions will be provided:
-
The heart rate is calculated from the module that its accessory is connected to the
monitor.
-
If two or more signals are being monitored simultaneously, the heart rate calculation will
be done based on the signals priority, i.e. ECG, SpO2, IBP1, IBP2, IBP3 or IBP4 signal
respectively.
-
If the heart rate is calculated from any signal except ECG, PR alarms will be enabled
based on HR alarm settings (Alarm Level and Alarm Limit).
