Rhythm control strategies in patients with atrial fibrillation (AF) can bring many clinical benefits. However, there is still uncertainty regarding selection of the optimal rhythm control strategy for persistent AF. Chronicity, substrate alteration, and underlying bradyarrhythmias could influence the clinical outcomes. Current guidelines do not provide a distinct recommendation for electrical cardioversion (ECV) in patients with AF with a slow ventricular response (SVR). We present two cases of sudden cardiac arrest due to sustained ventricular tachycardia/fibrillation after ECV of persistent AF with SVR.
节律控制策略在心房颤动（AF）患者中可以带来许多临床获益。然而，对于持续性 AF，选择最佳的节律控制策略仍然存在不确定性。慢性、基质改变和潜在的缓慢性心律失常可能会影响临床结果。目前的指南并没有为 SVR 持续性 AF 患者的电复律（ECV）提供明确的建议。我们报告了两例因 SVR 持续性 AF 行 ECV 后发生持续性室性心动过速/颤动导致心搏骤停的病例。
