8.7. ST Monitoring
ST segment of ECG waveform refers to the phase from the end of ventricular
depolarization to the beginning of ventricular repolarization, or from the end of QRS
complex (point J) to the beginning of T wave. ST segment analysis is mostly used to
monitor the oxygen supply and myocardial viability of patients. ST segment analysis
function is applicable to adults, pediatric and neonatal patients.
8.7.1. Safety Information
WARNING：
Factors such drugs, metabolism or conduction disorders may affect ST values.
Since ST is calculated by a fixed delay after point J, it may be affected by
changes in heart rate.
The data accuracy of ST algorithm has been tested, and its clinical significance
should be decided by doctors.
The monitor provides ST segment change information, and the clinical opinion
of this information should be decided by the doctor.
8.7.2. Enabling ST Monitoring
The ST segment analysis function is disabled by default. Please enable ST segment
analysis according to the following steps:
1. Select ECG parameter area or waveform area to enter 【ECG】 menu.
2. Select 【ST】 submenu【Setting】 submenu.
3. Switch on the 【ST Analysis】. The following clinical situations may make it
difficult to obtain reliable ST monitoring:
Lead with low noise cannot be obtained.
Arrhythmia leading to irregular baseline exists, such as atrial
fibrillation/atrial flutter.
The patient is continuously performing ventricular pacing.
The patient has left bundle branch block.
