Previous studies have suggested that fibrillatory substrates are widely distributed in both atria in patients with persistent atrial fibrillation. Extensive bi-atrial ablation has been increasingly performed to improve the clinical outcomes; however, this may adversely affect the intra-atrial conduction during sinus rhythm. The worst con- sequence of an intra-atrial conduction disturbance is conduction block between the atrium and atrioventricular node. There have been a few case reports on this complication, which suggest that the conduction block may occur more. This review aimed to describe the risk factors and method of prevention of atrium-atrioventric-ular node conduction block.
先前的研究表明，在持续性心房颤动患者中，颤动基质广泛分布于双侧心房。为改善临床结局，广泛的双房消融术应用得越来越多；然而，这可能会对窦性心律时的心房内传导产生不利影响。心房内传导障碍最严重的后果是心房与房室结之间的传导阻滞。关于这一并发症已有一些病例报告，提示传导阻滞可能更易发生。本综述旨在描述心房 - 房室结传导阻滞的危险因素及预防方法。
