We present a case of a 71-year-old woman with symptomatic paroxysmal atrial fibrillation and atypical atrial flutter (AFL), ultimately diagnosed with a rare type 3 macro-re-entrant biatrial tachycardia (BiAT). Despite initial pulmonary vein isolation and anterior line ablation for atypical AFL, she experienced recurrent AFL requiring a complex redo ablation. Successful termination of the tachycardia was achieved by extending ablation to the septal regions of both atria. This case highlights the complexity of managing BiAT.
我们报告一例71岁女性，患有症状性阵发性心房颤动和非典型心房扑动（AFL），最终诊断为罕见的3型大折返性双房性心动过速（BiAT）。尽管最初进行了肺静脉隔离和针对非典型AFL的前路消融，但她仍经历复发性AFL，需要进行复杂的再次消融。通过将消融扩展至双房的间隔区域成功终止了心动过速。该病例突出了BiAT管理的复杂性。
