Abstract

We report a case of atrioventricular (AV) block post successful percutaneous atrial septal defect (ASD) device closure. He had minimal fatigue and presented for his routine follow-up after intervention. His ECG showed 2:1 AV block. The interesting finding was appearance of varying PR interval in the conducted beats evoking possibility of complete heart block (CHB). We review the literature and conclude that changing PR is part of compensation to maintain R-R interval in a typical Wenckebach phenomenon.

ASD设备关闭后AV阻断-机制是什么？

我们报告一例房室（AV）阻滞后成功经皮房间隔缺损（ASD）装置关闭。他有轻微的疲劳，并在干预后进行了常规随访。心电图显示2:1房室传导阻滞。有趣的发现是在传导的心跳中出现不同的PR间隔，引起完全心脏传导阻滞（CHB）的可能性。我们回顾了文献，得出结论：在典型的Wenckebach现象中，改变PR是维持R-R区间的补偿的一部分。
