New concepts in the therapy of atrial fibrillation.

Atrial fibrillation is a frequent arrhythmia with increasing prevalence. The paper reviews the most important present aspects and paradigms in the treatment of the arrhythmia. The main aim of treatment is directed to improve the quality of life while reducing morbidity and mortality. A large experience derived from epidemiological registers and clinical research, impressive advances in interventional electrophysiological therapies and the introduction of non-vitamin K antagonists had a dramatic impact on the medical approach. Recommended steps to classify and treat atrial fibrillation are presented and discussed.
