Atrial fibrillation is the most commonly tachyarrhythmia clinically, with an increasing tendency of morbidity for getting older. Atrial fibrillation will cause palpitation, decrease in activity tolerance, decrease in quality of life, and even more serious resulting in cardiac failure, thromboembolic complication and so on. In the future, the Second Affiliated Hospital will take advantage of the construction of national atrial fibrillation center, strive for better progress in normalizing anticoagulation of atrial fibrillation, radiofrequency ablation, drug therapy and administration, and further improve the diagnostic rate and treatment rate of atrial fibrillation.Edited by Zhou Yuanyuan
