摘　　要：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 specif- ic 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 m, n = 7） Results The mean age of patients in group I , at （44 ± 14） year old, was less than that in groups II and lll, 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 m （ 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 Ill. Conclusions Si- nus P-wave prolongation and notching in young patients with a rapid AT without heart disease predicted an origin in the pulmonary vein.
