to adjust the ST measuring point in the following methods.
Method of Adjusting ISO and ST
Adjust the values by turning the knob.
Setting the measuring point of ST Segment, please open the “Determine Analysis Point” window
and the window will show QRS wave-group module (if the channel is not opened, “ST Analysis
Switch OFF” will be prompted). The location for high-brightness line in the window can be
adjusted. Select the ISO or ST first, and then turn the knob both leftward and rightward to move
such a line in parallel so as to determine the reference point or measuring point.
Caution
The abnormal QRS wave group will not be taken into consideration when ST segment is
analyzed.
Alarms & Reminders used in ST Segment Analysis.
Caution
The alarm limits for two measured values of ST SEGMENT are coincident. The alarm
limit of each channel can’t be set alone.
The alarm record switch in the related menu being opened, the physical alarm caused by the
parameter alarm super-limit will make the recorder automatically output the alarm parameter
values and related measured waveforms.
For the physical alarm, technical alarm and noticed information possible to happen in the ST
Segment Measurement, please see the following table.
