为探讨射频导管消融（ＲＦＣＡ）阻断左束支的方法及其可行性、安全性，对１１只山羊心脏的左束支施行ＲＦＣＡ。每只山羊放电８．８±４．１次，每次放电功率３２．０５±６．６２Ｗ、放电时间５９．１８±２８．６５ｓ、放电消融面积为４１．０±４０．４ｍｍ２，总放电时间４４４．１８±３０７．２４ｓ。放电消融的靶点位于主动脉瓣下方、室间隔后下部。有９只山羊的左束支被成功地完全阻断，未发生完全性房室阻滞或右束支阻滞。结果提示采用ＲＦＣＡ可以安全地阻断左束支
To explore the method of radio frequency catheter ablation (RFCA) blocking the left bundle branch and its feasibility and safety, RFCA was performed on the left bundle branch of 11 goats. Each goat discharged 8.8 ± 4.1 times, each discharge power 32.05 ± 6.62W, discharge time 59.18 ± 28.65s, discharge ablation area 41.0 ± 40.4mm2, the total discharge time 444.18 ± 307.24s. The target of discharge ablation is located below the aortic valve, the lower part of the ventricular septum. Left bundle branches of 9 goats were successfully and completely blocked without complete atrioventricular block or right bundle branch block. The results suggest that the use of RFCA can safely block the left bundle branch
