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.
Starch is a carbohydrate and exists in two types of molecules: amylose (linear) and amylopectin (branched). Most starch contains a mixture of these two molecules, generally with more amylopectin (65% to 85%).The reaction between amylose (even though it is often present in lesser amounts) and iodine is said to account for the intense color change seen.ost starch contains a mixture of these two molecules, generally with more amylopectin (65% to 85%).
