摘要
作者比较分析了20例无药状态下不能诱发出心动过速的旁道患者与20例诱发出心动过速旁道患者的电生理试验资料。研究组中14例使用异丙肾上腺素或阿托品后立即重复电生理试验,其中7例诱发出心动过速,诱发出心动过速的原因是正常房室传导系统顺传功能的改善。对旁道逆传功能不佳的患者仍难以诱发出心动过速。
A study group of 20 patients having accessory pathway (AP) but no inducible atrioventricular reentrant tachycardia (AVRT) in drug-free state was analysed and compared to data from a control group of randomly selected patients with inducible AVRT. 14 patients of the study group were restudied after administration of isoproterenol or atropine and AVRT became inducible in 7 patients. Ability to induce AVRT after administration of isoproterenol or atropine was due to the improvement of anterograde conduction over normal AV conduction system, but it remained difficult in patients with inadequate retrograde conduction over the AP.
