心房颤动(atrial fibrillation,AF)是临床最常见的心律失常,发病率为0.15%～1.00%,在二尖瓣病变患者中,心房颤动发生率高达40%～79%[1]。以往心房颤动多被看作是一种良性心律失常,然而近2O年来的研究结果表明,心房颤动是脑卒中的主要原因,同时也是充血性心力衰竭发展过程中的一个重要促进因素[2,3]。房颤发病率高、危害较大,针对房颤的治疗是近年来临床上研究重点之一。房颤的药物或电
Atrial fibrillation (AF) is the most common clinical arrhythmia, the incidence of 0.15% to 1.00%, in patients with mitral valve disease, the incidence of atrial fibrillation as high as 40% to 79% [1]. In the past, atrial fibrillation was considered as a kind of benign arrhythmia, however, the results of recent 2O years showed that atrial fibrillation is the main cause of stroke and an important contributing factor in the development of congestive heart failure [2,3 ]. The incidence of atrial fibrillation is high and the harm is greater. The treatment of atrial fibrillation is one of the focuses of clinical research in recent years.
