竇性心律下射頻導管消融起源于希蒲系統(tǒng)特發(fā)性室性心動過速的臨床觀察
袁義強 劉懷霖 于力 王瑞敏 孫運 趙育潔 孫俊華 牛思泉摘要 目的 探討竇性心律下射頻導管消融（RFCA）起源于希蒲系統(tǒng)特發(fā)性室性心動過速（IVT）的臨床結(jié)果。方法 23例起源于希蒲系統(tǒng)IVT，按消融方法分為兩組：⑴心動過速消融組，為9例患者，以心動過速下最早提前P電位為靶點，在心動過速下進行消融；⑵竇性心律消融組，為14例患者，以心動過速下記錄最早P電位且竇律下試放電過程中出現(xiàn)同形或近似室性早搏及短陣室性心動過速為靶點，在竇律下進行消融。術(shù)后反復程序刺激不能誘發(fā)心動過速為消融終點。觀察兩種不同消融方法的臨床結(jié)果。結(jié)果 兩組在手術(shù)成功率、手術(shù)時間、X線曝光時間、并發(fā)癥發(fā)生率及復發(fā)率方面無明顯差別。結(jié)論 竇性心律下射頻消融起源于希蒲系統(tǒng)IVT安全、有效。

[Abstract] Objective Study the clinical results of radiofrequency catheter ablation on idiopathic ventricular tachycardia from His-Purkinje system during sinus rhythm. Method 23 idiopathic ventricular tachycardias, from His-Purkinje system,were divided into two groups in accordance with radiofrequency catheter ablation methods:⑴Tachycardia ablation group, There are 9 patients, whose abltion target sites are the earliest P potentials during IVT.And this group was ablated during tachycardia.⑵Sinus rhythm group, there are 14 patients, whose ablation target site are the earliest P potentials during tachycardia, and the vent
