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 large linear chain (molecular weight 150,000-600,000) whose glucose units are connected by a,1:4 linkages. Amylose-the a,1:4 linkages are shown in red On the other hand, amylopectin (molecular weight 1-6 million), consists of many amylose chains joined together to form a highly branched structure.
