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.
1 Ventricular tachycardia. 2  Ventricular tachycardia is a rapid heart rate that originates with abnormal electrical signals in the ventricles. 3  The rapid heart rate doesn't allow the ventricles to fill and contract efficiently to pump enough blood to the body.
