Prevention of early recurrencies of atrial fibrillation in patients after ablation due to persistent form of atrial fibrillation

Atrial fibrillation is by far the most common cardiac arrhythmia. The prevalence of this disease in the general population is about 1-2% and is likely to increase over the next 50 years. Atrial fibrillation is accompanied by an increase in the incidence of stroke and other thromboembolic complications, the development of heart failure, the rate of hospitalization, a deterioration in the quality of life, and decreased exercise tolerance. The low efficiency of treatment of persistent atrial fibrillation, frequent relapses after interventional treatment determine the search for the optimal treatment option. The article discusses the main options for radiofrequency catheter ablation for persistent atrial fibrillation, as well as ways to prevent early recurrence of atrial fibrillation after catheter ablation. The effect of antiarrhythmic therapy on the prevention of early recurrence of atrial fibrillation after catheter ablation. Possibility of evaluating the effectiveness of antiarrhythmic therapy depending on the effective refractory period of the left atrium.
