7.6 ST Monitoring
The monitor performs ST segment analysis on normal and atrially paced
beats and calculates ST segment elevations and depressions.
ST segment monitoring fuction is not applicable to neonates.
The clinical significance of the ST segment analysis should be determined
by a physician.
Warning: Some clinical conditions may make it difficult to achieve
reliable ST monitoring, for example:
——
If you are unable to get a lead that is not noisy;
——
If the patient is continuously ventricularly paced;
——
If the patient has left bundle branch block;
——
If arrhythmias such as atrial fib/flutter are present, which may cause
an irregular baseline;
You should consider switching ST monitoring off if these conditions
are present.
