Identify the analysis point for ST segment.
Select the "DEF POINT" item in "ECG SETUP" menu, in which the value of ISO and ST point can be set.
1. ISO (Base point): to set the baseline point.
2. ST (Starting point): to set the measurement point.
The ISO and ST are the two measurement points in ST segment, both of them can be adjusted.
The reference point is the position where the peak of R-wave locates (as figure below). The ST measurement value for
each heartbeat complex wave is the difference between the two measurement points.
The position of measurement points (ISO and ST) should be adjusted at the beginning of monitoring, or the patient's HR
or ECG waveform changes significantly. Abnormal QRS complex is not considered in ST segment analysis.
NOTE:
l Abnormal QRS complex is not considered in ST segment analysis.
l The measurement points should be adjusted if the patient's HR or ECG waveform changes significantly,
detailed instructions are described in the following.
