  select [Arrh. Alarm Setup >>] to change alarm settings for individual arrhythmia 
events. For Mortara algorithm, Asystole, Vfib and Vtac are exclusively high-level 
alarms and their alarm level is unchangeable. Furthermore, these alarms will be 
triggered only if their alarm conditions are active, regardless of whether arrhythmia 
analysis is switched on. 
 
8.7.4 Changing Arrhythmia Threshold Settings (For Mortara 
Only) 
Select the ECG parameter window→[Arrh. Analysis >>]→[Arrh. Threshold Setup], and 
you can then change threshold settings for some arrhythmia alarms. In case an arrhythmia 
violates its threshold, an alarm will be triggered. The asystole delay time relates to 
arrhythmia relearning. When HR is less than 30 bpm, it is recommended to set the asystole 
delay time to 10 seconds.
