房颤是慢性心衰患者中最常见的持续性心律失常。其患病率和发病率随年龄增长及心衰加重而升高,在某些研究中上升到50%。心房收缩功能的丧失导致每搏量下降,灌注压升高及心房扩大。快速心室率及不规则心律进一步降低心脏充盈和排空。房颤影响慢性心衰预后的重要性已经在临床研究
Atrial fibrillation is the most common persistent arrhythmia in patients with chronic heart failure. Its prevalence and morbidity increase with age and heart failure, and in some studies have risen to 50%. The loss of atrial systolic function leads to a decrease in stroke volume, increased perfusion pressure and atrial enlargement. Rapid ventricular rate and irregular heart rhythm further reduce heart filling and emptying. The importance of atrial fibrillation in the prognosis of chronic heart failure has been in clinical research
