211例2月～15岁儿童进行食道心房调搏 (TEAP)电生理检查 ,发现49例房室结双径道 (DAVNP) ,其中12例(24.5% )在常规心电图上表现为I°房室传导阻滞 (I°AVB)、间歇性I°AVB、II°AVB呈不典型文氏现象等3种类型。提示I°～II°AVB也是小儿DAVNP引起的较为常见的心律紊乱 ,并探讨了DAVNP表现为AVB时的电生理特征及其临床意义
211 cases of children aged from 2 months to 15 years underwent esophageal atrial tamping (TEAP) electrophysiological examination and found that 49 cases of atrioventricular junctional pathways (DAVNP), of which 12 cases (24.5%) in the conventional ECG showed I ° atrioventricular Conduction block (I ° AVB), intermittent I ° AVB, II ° AVB were atypical Venturi phenomenon and other three types. Tip I ° ~ II ° AVB is also caused by DAVNP in children more common heart rhythm disorder, and to explore the electrophysiological characteristics of DAVNP showed AVB and its clinical significance
