摘    要:目的观察非接触式球囊标测系统(Ensite 3000系统)指导室性心动过速(室速)最早激动点标测和消融的优越性.方法对8例患者,经左右股静脉将64极球囊电极及大头导管置入右心室,Ensite 3000系统构建出心腔三维几何模型,诱发室速或室性早搏(室早)并记录储存,利用虚拟心内膜电图及导航系统进行室速最早激动点的标测和消融.结果8例患者均诱发及标测到起源于右心室的室速或室早,6例起源于间隔部,1例起源于游离壁,1例起源于室间隔与游离壁交界处,8例患者均在最早激动点获消融成功.结论En-site 3000系统对室速最早激动点的标测和消融更精确、直观和可靠.

关 键 词:非接触标测  室性心动过速  射频消融  最早激动点

Abstract:Objective To observe the results of mapping and ablating the earliest activation foci of ventricular tachycardia under the guide of non-contact balloon mapping system.Methods In8patients,a balloon electrode of64poles and a ablation catheter were positioned in right ventricle through left and right femoral veins to establish a three-dimensional model of right ventricle with Ensite3000system.Ventricular tachycardia or ventricular premature beat were induced and recorded.Stimulant endomyocardial electrocardio-gram and guide system were used to map and ablate the earliest activation foci of ventricular tachycardia.Re-sults Ventricular tachycardia or ventricular premature beat arising from right ventricle was induced and mapped in total of8patients,among whom in6cases those aring from septal part,in1case from the free wall and one from the common boarder of the interventricular septum and the free wall.Ablation at the earli-est activation foci was successful in all of the eight patients.Conclusions It is more precise,reliable and in-tuitional to map and ablate the earliest activation foci of ventricular tachycardia with Ensite3000system.
Keywords:Non-contact mapping Ventricular tachycardia Refrequency ablation The earliest activation foci
