心房颤动(Af)是临床上常见的心律失常之一,ATRIA研究表明Af的发生率为0.4%~1%〔1〕,随着年龄增高,Af的发生率将进一步增加。据报道Af的发生与肺静脉电位有关,而环肺静脉前庭电隔离(CPVA)可治愈Af,故肺静脉前庭是否是Af发生和维持的关键部位一直是争论的焦点。现就肺静脉前庭与A Atrial fibrillation (Af) is one of the most common clinical arrhythmias. ATRIA studies have shown that the incidence of Af ranges from 0.4% to 1% [1]. As the age increases, the incidence of Af increases further. It has been reported that the occurrence of Af is related to the pulmonary venous potential, and the pulmonary veins vestibular galvanic isolation (CPVA) can cure Af. Therefore, whether the vestibular veins of the pulmonary veins are the key sites for the occurrence and maintenance of Af has been the focus of controversy. Now pulmonary vestibule and A
