为提高体表希氏束电图的成功率,对52例正常心律及第Ⅰ度房室阻滞的病人同时进行了4个导联信号平均法的检测(后—前、对角线、Ⅴ_(?)—Ⅴ_(?)及垂直导联),42例获得清晰的希—浦氏电位(HP波)图(80.8%)。多导联记录可找到最大HP波向量和最小的心房终末电位的导联,并可更确切地辨认HP波起点,避免将束技波误为HP波的起点。因此,我们建议在体表记录希氏束电位时可常规应用多导联体系(后—前、对角线、Ⅴ_■—Ⅴ_■)。 In order to improve the success rate of body surface His bundle-beam imaging, the signal of 4 lead signals was detected simultaneously in 52 patients with normal rhythm and Ⅰ degree atrioventricular block (post-anterior, diagonal, Ⅴ_ (?) - V_ (?) And vertical lead), 42 patients obtained a clear Greek - Pu (Potentials) wave (HP) graph (80.8%). Multi-lead records can find the maximum HP wave vector and the minimum atrial terminal potential lead, and can more accurately identify the starting point of HP wave, to avoid the beam wave as the starting point of HP wave. Therefore, we recommend that multi-lead systems (post-front, diagonal, V_ ■ -V_ ■) be applied routinely when recording the His bundle potential on the body surface.
