Atrial fibrillation and flutter are characterized by disorganization of impulse conduction in cardiac atria. It results in decreased contractility; blood stagnation activates hemostasis and increases risk of thromboembolic stroke.
This risk is increased in patients after a stroke, diabetic patients, patients with hypertension, heart failure and older patients, in patients with postreumatic valve disease, coronary heart disease and females. According the risk antithrombotic treatment is indicated, especially anticoagulation treatment with warfarin.
In consistence with guidelines strategy of treatment and frequent situations from daily practice are discussed.
