The author researched risk factors for atrial fibrillation in 93 patients with atrial flutter after radiofrequency ablation of cavotricuspid isthmus. Effectiveness of radiofrequency ablation of the inferior isthmus was 93.5%. Before operation in 10% patients from the group of patients without atrial fibrillation, in postoperative period developed atrial fibrillation. Factors for this arrhythmia include elderly age, low contractility of the aortic ventricle of heart, dilation of the left atrium, chronicity and rate of arterial hypertension. In group of patients with atrial fibrillation in pre- and postoperative period this arrhythmia developed in 73.9% of patients. Risk factors for atrial fibrillation include elderly age, time duration of arrhythmic anamnesis and chronicity and rate of arterial hypertension.
