心房扑动:目前认识和治疗建议

Atrial flutter:Current knowledge and therapeutic recommendation

心房扑动 (房扑 )是房性心动过速的一个类型 ,近年的电生理研究和射频消融资料已经明确 ,房扑是起源自心房的大折返性房性心动过速的一种。由于电生理研究和射频消融资料的积累 ,对房扑的发生机制、分类、药物治疗以及非药物治疗等方面 ,都取得了重大进步。尤其导管射频消融近年发展迅速 ,已可作为有效治疗 ,也许是根治房扑的手段。为使广大临床医师了解和更好地治疗这个临床并不罕见的快速心律失常 ,中华心电生理和起搏学会房性快速心律失常专家组 ,对房扑的定义、电生理机制、分类、流行病学、预后、药物治疗和非药物治疗尤其射频消融的细节等方面 ,就目前的认识作了重点回顾 ,对适当的治疗提出了建议。

Atrial flutter(AFL),one type of atrial tachycardias,is less commonly observed in clinical practice than is atrial fibrillation.The mechanisms of some types of atrial tachycardias,including AFL,are now well understood,and the management for them were developed.Most cases of patients with typical AFL both clockwise and counterclockwise are now able to be cured by radiofrequency ablation approach.In order to match present understanding of mechanisms and therapy for AFL,the Chinese Society of Electrophysiology and Pacing organized an expert group to make a recommendation for the management of AFL,and is directed at electrophysiologists as well as clinical cardiologists with interests in arrhythmias.
