10.8.4 PVCs Alarms and Prompt messages
Among physiological alarms, those belonging to the type that the parameter has exceeded the limits may activate the
recorder to automatically output the parameters and related measured waveforms when the alarms occur on the
condition that the alarm record switch in related menu is On.
Possible physiological alarms and technical alarms during PVCs measurement are listed as below.

Arrhythmia alarm
The alarm is triggered when an Arrhythmia occurs. If the ALM is ON, the alarm sounds and the alarm indicator flashes.
If the REC is ON, the alarm record will be printed out (the ECG waveform of the channel being analysed 4 seconds
prior to and after the alarm).
Alarms and prompt messages related to arrhythmia analysis are listed as below:
