结论：对选择恰当的永久性房颤，持续口服负荷量胺碘酮转复率高、安全。
Conclusions: Continued oral load amiodarone has high rates of cardioversion and safety for the perpetual af with choice suitable.
结果：患者中阵发性房颤、持续性和永久性房颤分别占12％、22％、66％；
Results:The incidence of paroxysmal, persistent and perpetual atrial fibrillation patients were 12%, 22%, 66% respectively.
结论在有永久性房颤的病人中，温和的心率控制与严格的心率控制一样有效，而且更容易实现。
Conclusions In patients with permanent atrial fibrillation, lenient rate control is as effective as strict rate control and is easier to achieve.
持续性房颤患者还有可能是没进行或尝试心脏复律治疗的长期房颤患者，通常会导致永久性房颤。
Patients with persistent AF also include patients with long-standing AF in whom cardioversion has not been indicated or attempted, often leading to permanent AF.
我们假设，在有永久性房颤的病人中，在预防心血管并发症和死亡方面，温和的心率控制不劣于严格的心率控制。
We hypothesized that lenient rate control is not inferior to strict rate control for preventing cardiovascular morbidity and mortality in patients with permanent atrial fibrillation.
