Fig10-8 Determine the ST Segment AP
ISO and ST are two measuring points of ST Segment, which are adjustable.
R wave crest point is the reference point in setting of ST measuring point (as shown in the
following figure):
Fig 10-9 ST Analysis Point
ST measured value of each HB composite waveform is the vertical distance between this
waveform and the crossing of two measuring points.
Caution
Where obvious changes happen to the patient’s HR or ECG Waveform, it is necessary
