随机试验的证据表明双腔起搏的好处是非常有限的:①生理性起搏与单腔起搏比较,在死亡率和卒中方面不存在显著性差异;②DDD模式的慢性右室起搏导致的心室不同步引起心房颤动(AF)的发生率和心力衰竭住院率显著增加;③AF的起搏预防和治疗已显示出很少有效或无效;④生理性起搏器的
The evidence from randomized trials shows that the benefits of dual-chamber pacing are very limited: ① Compared with single-chamber pacing, there is no significant difference in mortality and stroke between physiological pacing; ②DVD-induced chronic right ventricular pacing Ventricular dysfunction caused by atrial fibrillation (AF) incidence and hospitalization rate of heart failure increased significantly; ③ AF pacing prevention and treatment has been shown to be less effective or ineffective; ④ physiological pacemaker
