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 response may be 1:1 or with varying degrees of AV block (especially in digitalis toxicity, as shown in this 3-lead ECG with 2:1 block).  Ectopic atrial rhythm is similar to ectopic atrial tachycardia, but with HR < 100 bpm.
