1. In the [
ST Analysis
] menu, select [
Adjust ST Points >>
]. In the [
Adjust ST Points
]
window, three vertical lines represent the ISO, J and ST points’ positions respectively.
2. Select [
View Leads
] and use the Knob to select an ECG lead with obvious J point and
R wave.
3. Select [
ISO
], [
J
] or [
ST
] and then use the Knob to adjust the position of each point.
‹
The ISO-point (isoelectric) position is given relative to the R-wave peak. Position
the ISO-point in the middle of the flattest part of the baseline (between the P and
Q waves or in front of the P wave).
‹ The J-point position is given relative to the R-wave peak and helps locating the
ST-point. Position the J-point at the end of the QRS complex and the beginning of
the ST segment.
‹ The ST-point is positioned a fixed distance from the J-point. Move the J-point to
position the ST-point at the midpoint of the ST segment. Position the ST-point
relative to the J-point at either J+60 or J+80.
8.7 About Arrhythmia Monitoring
Arrhythmia analysis provides information about your patient’s condition, including heart
rate, PVC rate, rhythm and ectopics. The arrhythmia detection is intended for adult and
pediatric patients.
WARNING
z
Arrhythmia analysis program is intended to detect ventricular arrhythmias. It is
not designed to detect atrial or supraventricular arrhythmias. It may incorrectly
identify the presence or absence of an arrhythmia. Therefore, a physician must
analyze the arrhythmia information with other clinical findings.
