本文报告用导管法描记希氏束电图20例的正常值并研究了20例本病患者的图形。将传导阻滞部位分为三个水平,其中房室结内阻滞、希氏束内阻滞及双侧束支阻滞分别占35％、10％与55％,多水平复合阻滞有4例。在此资料指导下对19例安装了心脏起搏器,均获得良好效果。希氏束电图能准确定位,特别是能判定多水平复合阻滞,对估计预后和选择起搏治疗等方面有肯定作用,具有较大的临床应用价值。 This article reports the normalization of the His bundle-echogram in 20 patients by catheterization and investigates the pattern of 20 patients with this disease. The conduction block is divided into three levels, of which atrioventricular block, His bundle bundle block and bilateral bundle branch block accounted for 35%, 10% and 55%, respectively, with multiple levels of 4 example. Under the guidance of this information on the 19 cases of pacemakers installed, have achieved good results. His bundle beam electrogram can be accurately located, especially to determine the multi-level composite block, the prognosis and selection of pacing treatment has a positive effect, with great clinical value.
