A patient presented with paroxysmal atrial fibrillation (AF) caused by focal rapid discharges arising from the ostium of the inferior vena cava (IVC). Surface ECG showed typical features of AF and flutter when rapid activation at the IVC ostium was conducted to the right atrium in a 1-to-1 and 2-to-1 fashion, respectively. Discrete radiofrequency energy applications at the medial ostium of the IVC completely eliminated the atrial tachyarrhythmias.
一名患者因下腔静脉（IVC）开口处局灶性快速放电而出现阵发性心房颤动（AF）。体表心电图显示，当IVC开口处的快速激动分别以1:1和2:1的方式传导至右心房时，出现典型的AF和扑动特征。在IVC内侧开口处进行离散射频能量应用完全消除了房性快速性心律失常。
