目的探讨EnSite 3000指导房性心动过速(简称房速)射频消融的临床疗效。方法回顾性分析2007年6月至2008年12月间11例症状明显,发作频繁的房速患者,在EnSite 3000指导下进行电生理标测,行射频消融。结果11例均取得手术成功,6例是局灶性房速,3例起源于左上肺静脉,3例分别起源左心耳基底部、上腔静脉和希氏束后方;5例是心房扑动(简称房扑),4例系瘢痕相关性,1例系三尖瓣峡部相关性。结论EnSite 3000指导下行房速的射频消融是安全有效的,且成功率高。
Objective To investigate the clinical efficacy of EnSite 3000-guided atrial tachycardia (referred to as atrial tachycardia) radiofrequency ablation. Methods A retrospective analysis of 11 patients with obvious symptoms and frequent seizures from June 2007 to December 2008 was performed electrophysiological mapping and radiofrequency ablation under the guidance of EnSite 3000. Results All of the 11 cases were successful in surgery, 6 cases were focal atrial tachycardia, 3 cases originated in the left upper pulmonary vein, 3 cases originated from the base of the left atrial appendage, the superior vena cava and His bundle, and 5 cases were atrial flutter Flutter), 4 cases of scarring correlation, and 1 case of tricuspid isthmus correlation. Conclusions EnSite 3000 radiofrequency catheter ablation guidance is safe and effective, and the success rate is high.
