Methods and Results— We conducted a randomized multicenter comparison of these 2 treatment strategies in patients with paroxysmal AF resistant to at least 1 antiarrhythmic drug.
AF converted to atypical atrial flutter(AFL) in 4 cases, but failed to terminate by ablation. AF converted to typical AFL in 2 cases, and terminated by tricuspid isthmus ablation.
消融术中房颤转为不典型房扑4例，消融未能终止，转为典型房扑2例，消融三尖瓣峡部均成功。
