目的探讨肺静脉起源房性心动过速的临床及心电图特点.方法收集2008年5月至2011年4月收治并行心内电生理检查确诊为房速的患者50例,根据房性心动过速起源位置的不同,将其分为三组:肺静脉房速(PV-AT,第一组)、肺静脉相关的房颤(第二组)、其他房速组(第三组).结果第一组患者的平均年龄为(44±14)岁,较第二组的(57±9)岁及第三组的(58±12)岁小(P＜0.05).第一组左房的内径(38±4) mm,较第二组的(48 ±7)mm及第三组的(49±5)mm小(P＜0.05).总之,肺静脉起源的房速的心动过速的周期较短,第一组和第二组的心动过速的周期分别为(289±45) ms、(300±48) ms,第三组额心动过速的周期为(392±106) ms.结论无器质性心脏病的年轻患者的窦P变宽并有切迹的房速起源于肺静脉.

Objective To investigate the clinical and electrocardiogram characteristics of specific to artial tachycardia originating from pulmonary veins (PV-AT),including sinus P-wave duration and notching.Methods The study included 50 patients underwent AT ablation,the patients were divided into three groups:those with PV-AT alone (group Ⅰ,n =25),those with PV-AT associated with atrial fibrillation (group Ⅱ,n =18),and those with other forms of AT (group Ⅲ,n =7).Results The mean age of patients in group Ⅰ,at (44 ±14) year old,was less than that in groups Ⅱ and Ⅲ,at (57 ± 9) year old,and (58 ± 12) year old,respectively (P ＜ 0.05) and the left atrial diameter,at (38 ±4)mm,was less than that in the other left AT groups:(48 ±7)mm in group Ⅱ and (49 ±5)mm in group Ⅲ (P ＜ 0.05).Overall,PV-AT presented with a short cycle length:(289 ± 45) ms and (300 ±48)ms in Group Ⅰ and Ⅱ,respectively,versus (392 ± 106)ms in Group Ⅲ.Conclusions Sinus P-wave prolongation and notching in young patients with a rapid AT without heart disease predicted an origin in the pulmonary vein.
