Pulmonary vein isolation in a dual-chamber pacemaker patient using the pulmonary vein ablation catheter (PVAC) system resulted in perpetual induction of ventricular tachycardia (VT) during radio frequency energy application. Induction of VT was abolished by programming the PVAC-system to a pure bipolar ablation mode. Patients with implanted devices should be closely monitored when using the PVAC system in unipolar modes.
在使用肺静脉消融导管(PVAC)系统对双腔起搏器患者进行肺静脉隔离时,在应用射频能量时会导致持续性室性心动过速(VT)的诱发。通过将 PVAC 系统编程为纯双极消融模式,可消除 VT 的诱发。在使用 PVAC 系统进行单极模式时,应密切监测植入设备的患者。
