Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice and induces cardiac dysfunction and strokes. The development of AF requires a"trigger" and also an electroanatomic "substrate" capable of both initiating and perpetuating AF. Over the past decade, the understanding of the AF substrate properties in both atria has increased with fractionation and frequency analyses of the local atrial electrograms using three-dimensional electroanatomic mapping systems. The purpose of this review was to discuss the differences in the atrial substrate properties in patients with different types of AF.
心房颤动（AF）是临床实践中最常见的持续性心律失常，可导致心脏功能障碍和中风。房颤的发生需要一个“触发因素”，还需要一个能够启动并维持房颤的电解剖“基质”。在过去十年中，通过使用三维电解剖标测系统对局部心房电图进行碎裂和频率分析，人们对两个心房中房颤基质特性的认识有所增加。本综述的目的是讨论不同类型房颤患者心房基质特性的差异。
