自1984年底起对17例儿童心脏病患者进行了心内希氏束图记录,必要时加心房调搏。本文报告房室传导阻滞者7例的检查,包括Ⅱ度Ⅰ工型阻滞3例,2:1阻滞1例,Ⅲ度阻滞3例。检查方法选用右下股静脉以 Seldimger 法经皮肤穿刺(年龄较小者则用切开法分出大隐静脉分支),以7号三极导管电极送入三尖瓣环上部,使电极尽可能接触希氏束部位。电极尾端通常以远端及中间电极连接前极放大器。滤过频带40～600Hz,输入 Mingogra-ph34四导心电图机(Siemens 公司),自上而下依次为心电图Ⅰ,Ⅱ,Ⅲ导联,希氏束图。
From the end of 1984 onwards, 17 cases of children with heart disease underwent intracardiac His bundle mapping, if necessary, add atrial pacing. This report of atrioventricular block in 7 cases of examination, including Ⅱ degree Ⅰ block in 3 cases, 2: 1 block in 1 case, Ⅲ degree of block in 3 cases. Check the method of selection of the right lower femoral vein by Seldimger method of skin puncture (the younger were divided by saphenous vein incision) to the No. 7 triode catheter electrode into the upper tricuspid annulus, the electrode to make May contact His bundle. The end of the electrode is usually connected to the front amplifier with the far end and the middle electrode. Filtration band 40 ~ 600Hz, input Mingogra-ph34 four-lead ECG machine (Siemens company), top to bottom ECG Ⅰ, Ⅱ, Ⅲ leads, His bundle diagram.
