ECG Monitoring
8-16
1) Select the ECG parameter area or waveform area to enter [ECG] menu.
2) [Arrhythmia] tab → [Threshold] tab.
3) Set the threshold for all kinds of arrhythmias.
The setting of [Asystole Delay] is associated with ECG relearning. When HR is below 30 bpm, it is
recommended to set [Asystole Delay] to 10s.
8.5.3.4 Arrhythmia Threshold Range
1.5s, 2.0s, 2.5s, 3.0s, 3.5s
0min, 1min, 2min, 3min, 4min, 5min, 10min, 15min, 30min
8.6 Heart Rate Variability
HRV (heart rate variability) are statistical results calculated from consecutive RR intervals to reflect the variability
of sinus heart rate. The main mechanism of its occurrence is that the heart rhythm is directly regulated and
restricted by both cardiac sympathetic and vagal nerves. HRV analysis is a commonly used quantitative index to
identify autonomic nervous activity. It is of great clinical significance since it can be used to predict sudden cardiac
death, and evaluate the pathological state related to the activity and balance of cardiac autonomic nerves.
8.6.1 Enter HRV Menu
1) Select the ECG parameter area or waveform area to enter [ECG] menu.
2) Select [Setup] tab and then [HRV] button at the bottom of the menu to enter HRV menu.
