In some patients with atrial fibrillation, atrial flutter develops after administration of class IC antiarrhythmic drugs, the so-called class IC atrial flutter. Radiofrequency ablation of the right atrial isthmus results in clinical improvement in 85% of patients and provides an alternative management strategy for a subset of patients with therapy-resistant atrial fibrillation.
在一些心房颤动患者中，使用IC类抗心律失常药物后会发生心房扑动，即所谓的IC类心房扑动。对右心房峡部进行射频消融可使85%的患者临床症状改善，并为一部分药物难治性心房颤动患者提供了另一种治疗策略。
