We report the case of a 71-year-old man with two atrial tachycardias evolving simultaneously and independently in two dissociated regions after extensive ablation for chronic atrial fibrillation. One tachycardia was a focal tachycardia originating from the right inferior pulmonary vein and activating the posterior left atrium with a 2:1 conduction block, while the other tachycardia was an atrial flutter circulating around the tricuspid annulus, activating the right atrium and the anterior wall of the left atrium. These two atrial tachycardias were successfully ablated prior to restoration of sinus rhythm.
我们报告了一例71岁男性患者，在因慢性心房颤动接受广泛消融术后，两个房性心动过速在两个分离区域同时且独立地演变。一种心动过速是起源于右下肺静脉的局灶性心动过速，以2:1传导阻滞激活左心房后壁，而另一种心动过速是围绕三尖瓣环循环的心房扑动，激活右心房和左心房前壁。这两种房性心动过速在恢复窦性心律之前均成功消融。
