Atrial fibrillation is the most frequent arrhythmia seen in clinical practice. It occurs most commonly on patients with hypertensive, isquemic and valvular heart disease as well as in patients without cardiac disease principally in elderly patients. Due to the morbidity rate associated with it (atrial fibrillation), early diagnosis and adequate treatment is necessary in order to reduce any associated complication and to improve the health related quality of life of patients who suffer from it.
