随着心脏电生理研究的进展,房室结内双径传导日益受到重视。现对25例房室结内双径传导试作分析,以探索其临床电生理上的特性。资料和方法一、病人年龄16～57岁,男12例,女13例。25例中有室上性心动过速发作史者7例。二、检查前3天病人停用心血管药物。检查时在X线下用经皮穿刺术由股静脉插入 With the progress of electrophysiological study of the heart, more and more attention has been paid to the dual-conduction in atrioventricular node. Now 25 cases of atrioventricular nodal conduction test analysis to explore the clinical electrophysiological properties. Materials and methods A patient aged 16 to 57 years old, 12 males and 13 females. Twenty-five patients had episodes of supraventricular tachycardia in seven cases. Second, check the patient 3 days before the withdrawal of cardiovascular drugs. Inspected by X-ray percutaneous puncture by the femoral vein insertion
