ECG/RESP Monitoring
established, the system will display message "ST analysis key off!"). You can adjust the
position of the highlighted line in the window. The method is first select ISO or ST, then turn
the knob clockwise or counterclockwise to move the highlighted line horizontally so as to
define the reference point or the measurement point.
ZlA Note ^-lA
Abnormal QRS complex is not considered in ST segment analysis.
ST Alarm Message
If the alarm recording switches in relevant menus are set to ON, the physiological
alarms caused by parameter exceeding alarm limit can trigger the recorder to
automatically output alarming parameter value and corresponding measuring
waveform.
Tables below list out possible physiological alarms, technical alarms and prompt messages
that may occur during ST measurement.
Physiological alarms:
Message Cause Alarm Level
ST TOO HIGH ST measuring value is above the upper User-selectable
alarm limit.
ST TOO LOW ST measuring value is below the lower User-selectable
alarm limit.
Technical alarms:
Message Cause Alarm Level Remedy
ST ALM LMT ERR Functional safety failure HIGH Stop using ST alarming
function, notify
biomedical engineer or
Mindray service staff.
Prompt messages (include general alerts):
Message Cause Alarm Level
ST EXCEED ST measuring value exceeds the measurement HIGH
range.

Arrhythmia Analysis
The arrhythmia algorithm is used to monitor ECG of neonate and adult patient in clinical,
detect the changing of heart rate and ventricular rhythm, and also save arrhythmia events and
