changes needs to be determined by a clinician.
■
ST segment monitoring function is shutoff by default. You can switch it to ON when necessary.
Note
When setting ST ANALYSIS on, the monitor will select “DIAGNOSTIC” mode. You can set it to
“MONITOR” mode or “OPERATE” mode as required. However at this time ST value has been severely
distorted.
■
It is available to measure the variance of ST segment with ST analysis at the waveform tracks for selected lead.
The corresponding ST measurement result displays numerically at ST1 and ST2 in the Parameter Area. The trend
can be viewed with table or graphic form.
■
Measurement unit of ST segment: mV.
■
Measurement symbol of ST segment: "+" = elevating, "-" = depressing.
■
Measurement range of ST segment: -2.0 mV, ~ + 2.0 mV.

ST analysis alarm setting
ST ANAL: the switch for ST analysis. Set it to ON to activate the ST analysis or OFF to disable the ST analysis.
ST ALM: pick "ON" to enable prompt message and data record during the ST analysis alarm; pick "OFF" to
disable the alarm function, and there will be a
beside ST. ST alarm is activated when the result exceeds set
ST HI value or falls below ST LO value.
ALM LEV: used to set up the ST alarm level. There are three selections: HIGH, MED and LOW.
ALM REC: pick "ON" to enable report printing upon ST analysis alarm.
ALM HI: used to set up the upper limit of ST alarm. The max. higher limit is 2.0. The minimum higher limit is
0.1 larger than the set lower limit.
ALM LOW: used to set up the lower limit of ST alarm. The minimum lower limit is –2.0. The max. lower limit is
0.1 lower than the set higher limit.
