When the ECG signal is 80 BPM, the interval of the T wave is 180 ms, and the QT period is 350 ms.
ST Signal Processing and Display
ST segment deviation is defined as the movement above or below the equipotential level (mm).
The difference measurement compares the isoelectric point with the ST measurement point. The
isoelectric point defines a zero volt point (no electrical activity, 0 mm) with a base position on the
horizontal axis (in hours) of 28ms before QRS complex generation. In the ST segment, the ST
point occurs between the QRS offset (J point) and the T-wave. The default position is 80ms after
the QRS offset.
The ST analysis method examines ECG signals classified as “normal” beats on up to seven selected
ECG leads. The monitor measures the ST level of the normal bit ECG signal and displays the
deviation from the average ST level value. If ST monitoring is active, the trend of the ST level can
be reviewed in the trend display window.
Alarm and Alarm Status
High P-wave and T-wave, Long P-wave or T-wave with high amplitude duration can be detected by
QRS Complex. Place the leads on the ECG1 channel with the highest R-wave (compare to T-wave
and / or P-wave) to allow the monitor to properly detect low heart rate conditions in this situation.
If the monitor continues to misinterpret the P-wave or T-wave, use a pulse oximeter to reposition
the electrodes or monitor the animal's pulse rate.
