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.
A complex polysaccharide carbohydrate consisting of chains of linked glucose molecules. Amylose is a chain of 200 to 500 glucose units. Amylopectin consists of 20 cross-linked glucose molecules. Most natural starches are a mixture of these two. Starch, in the form of potatoes, rice and cereals forms an important part of the average diet and about 70% of the world's food.
