Two unusual cases of Wenckebach-like conduction block in the infranodal tissues which developed after an intravenous dose of a Class I antiarrhythmic drug are presented. The first case shows infra-Hisian Wenckebach during sustained atrioventricular nodal reentrant tachycardia. The second case demonstrates rate-dependent Wenckebach-like exit block between the pacing catheter and the right ventricular tissues during pacing.
本文报告两例不寻常的病例,患者在静脉注射一剂I类抗心律失常药物后,在结下组织出现类似文氏传导阻滞的情况。第一例显示在持续性房室结折返性心动过速期间出现希氏束下文氏现象。第二例显示在起搏过程中,起搏导管与右心室组织之间出现频率依赖性类似文氏现象的出口阻滞。
