虽然有报道肺静脉有时作为一个局灶性驱动器的心房颤动（AF），很少有报道有关的贡献，上级腔静脉（SVC）的AF的维持。在这里，我们报告一个持续性AF的患者由于局灶性放电后，肺静脉隔离程序的SVC。在多电极篮状导管标测引导下，分步射频电流应用首先将致心律失常的SVC与右心房断开，然后消除心动过速。
Although it has been reported that pulmonary veins sometimes act as a focal driver of atrial fibrillation (AF), little has been reported concerning the contribution of the superior vena cava (SVC) to the maintenance of AF. Here we report a patient with sustained AF due to focal discharges inside the SVC after pulmonary vein isolation procedure. Stepwise radiofrequency current applications with the guide of multielectrode basket catheter mapping first disconnected the arrhythmogenic SVC from the right atrium and then eliminated the tachycardia.
