１８５例６个月～１５岁小儿行食道心房调搏检查，发现房室结双径道（ＤＡＶＮＰ）４１例，三径道３例。４４例中有６例（１１．１％）引起阵发性室上性心动过速（ＰＳＶＴ），１０／４４例（２２．７％）在常规心电图（ＥＣＧ）上表现为Ｉ度房室传导阻滞（Ｉ°ＡＶＢ）、问歇性Ｉ°ＡＶＢ、Ⅱ°ＡＶＢ呈不典型文氏现象等三种类型。提示ＰＳＶＴ与Ｉ～Ⅱ°ＡＶＢ也是小儿ＤＡＶＮＰ引起的较为常见的心律紊乱现象，探讨了ＤＡＶＮＰ引起ＰＳＶＴ或ＡＶＢ的电生理类型及发生机理。
185 cases of 6 months to 15 years old children underwent esophageal atrial pacing examination found that 41 cases of DAVNP, three-track three cases. Six of the 44 patients (11.1%) developed paroxysmal supraventricular tachycardia (PSVT) and 10/44 (22.7%) showed I degree atrioventricular conduction on a conventional electrocardiogram Block (I ° AVB), intermittent intermittent I ° AVB, Ⅱ ° AVB was not typical of three types of Wen’s phenomenon. It is suggested that PSVT and I ~ Ⅱ ° AVB are also common phenomenon of arrhythmias induced by DAVNP in children. The electrophysiological types and mechanism of DAVNP induced by PSVT or AVB are discussed.
