Sucrose esters and sucrose oligo esters are normally identified by the source of fatty acids, containing either mostly palmitic or mostly stearic fatty acids (coded with P or S) and the. mono-ester content or the HLB-value. The mono-ester content determines the HLB-value so. usually either one is chosen.
A ventricular ectopic beat (VEB) is an extra heart-beat originating in the lower chamber of the heart. This beat, also called a premature ventricular contraction (PVC), occurs before the beat triggered by the heart's normal function.
The most common type of ventricular ectopic beat is premature, causing ventricular contraction before the underlying rhythm would normally depolarise the ventricles. The resultant heartbeat morphology on the ECG often appears wider and taller than that seen with the underlying rhythm.
