心房颤动 (简称房颤 )是临床上常见的心律失常 ,其发病率随着年龄增加而增加。据统计 ,6 5岁以上老年人群中房颤的发生率为 3%～ 5 % ,6 0岁后每 10年发生率增加 1倍 ,80岁后发生率可达 8%～ 10 %。房颤的主要危害是增加脑梗死的危险 ,并可使心排血量下降 ,长期房颤伴快速心室 Atrial fibrillation (atrial fibrillation) is a clinically common arrhythmia, the incidence of which increases with age. According to statistics, the incidence of atrial fibrillation in the elderly population over 5 years old is 3% -5%, the incidence of atrial fibrillation is increased by 10 times every 10 years after 60 years old, and the incidence rate is 8% -10% after 80 years old. The main hazard of atrial fibrillation is to increase the risk of cerebral infarction, and cardiac output can be reduced, long-term atrial fibrillation with rapid ventricular
