The term atrial flutter was introduced 90 years ago for an arrhythmia with a unique electrocardiographic pattern. The development of endocardial mapping techniques in the last decade allowed the detailed characterization of the tachycardia circuit and the identification of the cavotricuspid isthmus as its critical part. This review stresses the position of atrial flutter in the new classification of atrial tachycardias and focuses on its unique electrophysiological characteristics and different variants described in humans. Transcatheter radiofrequency ablation across the cavotricuspid isthmus constitutes a feasible and safe therapy, which prevents flutter recurrences during the long-term follow-up. This paper describes the different techniques that validate bidirectional isthmus block, which is an important endpoint for successful ablation.
“心房扑动”这一术语于90年前被引入，用于描述一种具有独特心电图模式的心律失常。过去十年中的心内膜标测技术发展，使得能够详细描绘心动过速环路，并确定腔静脉-三尖瓣峡部是其关键部分。本综述强调心房扑动在房性心动过速新分类中的地位，并着重介绍其独特的电生理特征以及在人类中描述的不同变体。经导管在腔静脉-三尖瓣峡部进行射频消融是一种可行且安全的治疗方法，可在长期随访中预防扑动复发。本文描述了验证双向峡部阻滞的不同技术，双向峡部阻滞是成功消融的重要终点。
