目的探讨心房颤动(简称房颤)患者肺静脉电隔离后发生肺静脉自发电位的相关因素.方法 153例患者,其中阵发性房颤114例,持续性或永久性房颤39例,术前行肺静脉CT血管造影并测量肺静脉最大直径,行环肺静脉消融肺静脉电隔离术,并进行肺静脉自发电位标测及其相关因素评价.结果术中,69例(45.1%)共125根肺静脉(20.1%,125/621)标测到自发电位.左上肺静脉最大径(LSPV,18.5±4.0mm)及右上肺静脉最大径(RSPV,18.7±4.2 mm)均大于左下肺静脉(LIPV,15.2±3.0 mm)及右下肺静脉(RIPV,16.3±3.8 mm)(P均＜0.001),右侧肺静脉大于左侧肺静脉(17.5±4.2 mm vs 16.8±3.9 mm,P=0.012);有自发电位的RSPV最大径大于无自发电位的RSPV(20.0±3.8 mm vs 18.3±4.3 mm,P=0.027).右侧肺静脉自发电位发生率高于左侧肺静脉(25.5%vs 15.1%,P=0.002),RSPV和RIPV自发电位发生率均高于LIPV(27.2%,23.8% vs 11.4%,P＜0.001与P=0.005).RSPV自发电位发生率与RSPV最大径正相关(β=0.097,P＜0.05).结论肺静脉最大径越大则自发电位的发生率越高,而RSPV有无自发电位与RSPV最大径明显相关.
