The methods are different from the HR Averaging Method of the monitor. Therefore,
the ventricular HR values calculated by basic/advanced ARR algorithm may be
different from the HR values calculated by HR Averaging Method. The ventricular HR
is for judging arrhythmias and is not exactly equal to the HR displayed on the
interface.
4 The ARR analysis results and HR values obtained during ARR analysis and HR
calculation are not affected by the selected filter mode. The algorithm itself has
independent data-flow processing, which can better ensure the consistent and
accurate results in different filter modes.
5 Atrial fibrillation alarm should meet below two conditions for 1 minute:

The RR interval of normal beats must be irregular,

It can be seen that the obvious f or P waves do not exist.
6 Atrial fibrillation analysis is only applicable to adult patients and should not be
performed for PVC or pacing fluctuations.
7 Atrial flutter cannot be detected by the atrial fibrillation algorithm because most of
their RR intervals are regular.
8 In following situations, atrial fibrillation alarm detection error may occur:

Sinus arrhythmia

Atrioventricular block

Frequent ventricular premature beats

Myoelectric interference

Electrode motion artifact
9.9.2 ARR Analysis Menu
9.9.2.1 Switching ARR Analysis On and Off
To switch ARR Analysis on or off, in the ECG Setup menu, select ARR Analysis to toggle
between On and Off from the popup interface.
9.9.2.2 ARR Alarm Setup
Select ECG Setup > ARR Analysis > ARR Alarm Setup to change the following ARR alarm
settings:
 Separately switch on or off each arrhythmia alarm and set the alarm level/record.
 Select All Alarms On/All Alarms Off to switch on or off all arrhythmia alarms except key
ARR alarms.
 Set the threshold of certain arrhythmia alarms. When an arrhythmia exceeds its threshold, an
alarm will be triggered.
 Select Default to restore the ARR alarm settings to factory defaults.
Confirm the changes to make the settings effective.
