本文报道5例在迷走神经刺激,中止SVT后得以检出具有WPW的心动.从而引起对潜伏性房室旁路的重视。众所周知,由房室旁路参与的折返性心动过速在室上性心动过速中所占比例,比早先估计的要多,因为常以潜伏的形式存在,造成诊断上的困难,而迷走神经刺激法可以是揭示潜伏性房室旁路的简便方法。 This article reports 5 cases of vagus nerve stimulation, suspend the SVT to be detected with WPW heartbeat.Thus cause the attention of latent atrioventricular bypass. It is well-known that reentrant tachyarrhythmias involving atrioventricular bypass account for a greater proportion of supraventricular tachycardias than previously estimated because they often exist in a latent form that causes diagnostic difficulties while vagal stimulation Law can be a convenient way to reveal latent atrioventricular bypass.
