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.
Ventricular Septal Defect. A ventricular septal defect (VSD) is a hole in the part of the septum that separates the ventricles. (The ventricles are the lower chambers of the heart.). A VSD allows oxygen-rich blood to flow from the left ventricle into the right ventricle, instead of flowing into the aorta as it should.entricular Septal Defect.
