摘要
目的 研究经胸二维超声心动图 (two dimensionalechocardiography ;2 DE) ,引导冠状窦电极导管 (coro narysinuselectriccatheter;CSEC)置放入冠状静脉窦 (coronarysinus ;CS)的可行性。方法 40例顺序行心内电生理检查的患者 ,随机分为 2 DE引导 (A组 )和X线引导 (B组 )行CSEC放置。结果 A、B二组放置CSEC的成功率分别为 95 %和 10 0 % (P >0 0 5 ) ,放置时间分别为 4 8± 5 2min和 4 1± 2 3min(P <0 0 5 ) ,二组患者均无并发症。结论 2 DE引导可大部分取代X线引导置放CSEC。
Objective To assess the value of two\|dimensional echocardiography (2\|DE) as image guide in determing coronary sinus catheter (CSC) position and controlling advancement of CSC. Methods with continued 40 patients needed intracardial electrophysiologic studies,2\|DE (20 patient,group A) or X\|ray (other 20 patients,group B) was used as image guide to determine the position of CSC. Results The success rate of determing CSC in site was 95% in group A and 100% in group B ( P >0 05). The operation time needed in A and B was 4 8±5 2 and 4 1±2 3 minute individually ( P >0 05),The exposure time of X\|ray in A and B group was 0 15±0 minute and 3 2±2 1 minute individually ( P <0 001). Conclusion 2-DE as image guide,could be used to determine CSC position and control advancement of CSC instead of X\|ray except of over obesity patient. [
