Пароксизмальная форма фибрилляции предсердий

Atrial fibrillation is one of the most commonly encountered disorders of heart rhythm. Atrial fibrillation results from a number of diseases such as heart defects (primarily mitral defects), thyroid dysfunction, lond-standing essential hypertension, and alcohol abuse. In some instances, the cause of atrial fibrillation remains unclarified. Atrial fibrillation can be asymptomatic for a long time. This fact is responsible for late diagnosis and it hampers the choice of optimal therapy. ACC/AHA/ESC 2006 guidelines for the management of patients with atrial fibrillation

present in detail an updated version of the clinical classification of atrial fibrillation and algorithms for the choice of optimal drug therapy with regard to arrhythmia duration, concurrent diseases and clinical pharmacology of the drugs. The Recommendations provide well-defined indications for electric cardioversion, substantiate regimens of anticoagulant therapy, and give a detailed comparative evaluation of different antiarrhythmic drug classes taking into account results of multi-center controlled studies. The Recommendations of the European Society of Cardiologists outline approaches to management of patients with atrial fibrillation from the standpoint of evidence based medicine.
