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 fibrillation. Ventricular fibrillation (V-fib) is a type of arrhythmia, or irregular heartbeat that affects your heartâs ventricles. Your heart is a muscle system that contains four chambers; the two bottom chambers are the ventricles.ecause V-fib can lead to cardiac arrest and death, it requires immediate medical attention. A defibrillator is an electronic device used to treat V-fib. It produces an electric shock that can restore a normal heartbeat.
