The differential diagnosis of bigeminal rhythms. Wing JP, Phibbs B. Bigeminal rhythms may arise from ectopic firing or from failure of impulse generation or conduction. In atrial bigeminy a premature atrial beat beat follows each sinus beat. If the PAC is not conducted bradycardia may result; if it is symptomatic treatment with digitalis or quinidine is indicated.
Intrinsically resistant to digestion and contains high amounts of amylose.Found in: fruits, potatoes, hi-maize RS products, corn, some legumes.Note: the more ârawâ or âuncookedâ a food is, the more RS it tends to have, since heat results in gelatinization of starch â making it more accessible to digestion.
Amylopectin starch, which is easy to digest and absorb, is a much larger molecule, containing 10,000 to 100,000 glucose units. At the molecular level amylopectin is highly branched. The large size and branching forms starch granules that are less dense and gelatinize (absorb water) easily when heated in water.Resistant starch escapes digestion and absorption yet is fermentable by the bacteria common to the large intestine, including Bifidobacterium, Clostridium, Bacteroides, Fusobacterium and Butyrivibrio.â. To the casual reader, this doesnât say much.
