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.
Amylose is a helical polymer made of Î±-D-glucose units, bonded to each other through Î±(1â4) glycosidic bonds. This polysaccharide is one of the two components of starch, making up approximately 20-30% of the structure. The other component is amylopectin, which makes up 70â80% of the structure.
