心房颤动(房颤)是临床常见的心律失常,除部分病人经药物或电击复律成功外,其余病人长期处于房颤状态。此时治疗房颤的目的在于控制心室率。一般认为心室率应控制在60～100次/分为好。迄今,有关房颤时最佳心室率的选择的研究尚少见。本文通 Atrial fibrillation (atrial fibrillation) is a common clinical arrhythmia, in addition to some patients with drug or shock cardioversion success, the remaining patients with long-term atrial fibrillation. At this point the purpose of treatment of atrial fibrillation is to control ventricular rate. Generally believed that the ventricular rate should be controlled at 60 to 100 times / divided into good. So far, the study on the choice of the best ventricular rate during atrial fibrillation is still rare. This article pass
