本文报道19例因心脏后侧房室附加束所致致命性心动过速病人应用标准除颤脉冲行导管消蚀术的结果。重点探讨该技术的限度和分析有利于成功的因素。方法:23例病人经电生理检查,20例附加束位于后间隔,2例在左后游离壁。1例爱勃斯坦畸形患者有两条附加束,一条在后间隔,另一条在右后游离壁。术前作冠状动脉造影,在消蚀放电处冠状窦段20m This article reports the results of 19 cases of patients with fatal tachycardia due to the additional bundle of the posterior chamber of the heart using standard defibrillation pulse catheter ablation. Focus on the limits of the technology and analyze the factors that contribute to success. METHODS: Twenty-three patients were examined by electrophysiological examination, with 20 additional posterior compartments located in the posterior compartment and 2 posterior left posterior wall. One case of Love Beisteel deformity patients have two additional bundles, one after the interval, the other in the right posterior free wall.
