An intraatrial reentrant circuit was identified using an electroanatomical mapping system and evaluation of postpacing intervals in a patient with tricuspid annulus. Intraatrial reentrant tachycardia was successfully eliminated on the basis of the interpretation that the reentry circuit depends on a congenitally closed tricuspid annulus. We report that a congenitally closed tricuspid annulus is one of the anatomical obstacles when we consider atrial tachyarrhythmia.
使用电解剖标测系统并评估三尖瓣环患者的起搏后间期，确定了一个房内折返环。基于折返环依赖先天性闭合三尖瓣环的解释，房内折返性心动过速得以成功消除。我们报告，当考虑房性快速性心律失常时，先天性闭合三尖瓣环是解剖学障碍之一。
