10.6 ECG Alarm and Prompt Message
11.6.1 Alarms
Alarms occurring in the process of ECG measurement contain two types: physiological alarm and technical alarm.
Prompt messages may also appear in the mean time. For the audio and visual features during the appearance of these
alarms and prompt messages, please refer to the related description in
Chapter 5 Alarm
. In the screen, physiological
alarms and prompt messages (general alarms) are displayed in the physiological alarm area of the monitor, while
technical alarms, and prompt messages that unable to trigger alarms are displayed in the technical alarm area. This
section does not describe the alarm part about arrhythmia and ST analysis.
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.
Tables below describe respectively the possible alarms those may occur during the measurement.
Physiological alarms:
