Abstract
This work deals with atrial fibrillation (AF) and its classification in electrogram recordings. The heart must deliver enough blood for the body to function normally: according to a model developed by Guyton this depends on the heart rate, the average pressure in the right atrium, the total amount of blood and the vasal resistances and compliances. It is equally important, though, that blood is pumped correctly, in respect to the constraints that its particular nature imposes, in order to avoid coagulation and hemolysis, and to the omeostasis of the human body. Correct hemodynamic and pressure values are then fundamental for the normal function of the body: hemodynamically, the atria work as collection and suction chambers during diastole and booster pumps during systole while, electrically, they work as impulse generators and current distributors.
