Abstract：
A 74-year-old woman with an implanted physiological DDD pacemaker visited our department complaining of palpitations due to atrial fibrillation (AF). Catheter ablation therapy for AF was scheduled. Preoperative multidetector computed tomography showed that the inferior pulmonary vein (PV) was a common trunk, and the left and right superior PVs branched from the center of the left atrial roof. In addition, mapping of the left atrium before AF ablation revealed no potential in either the inferior PV or common trunk. We performed left and right superior PV and posterior wall isolation. After ablation, AF was not observed on pacemaker recordings.
摘要：
一名74岁的女性植入了生理DDD起搏器，因房颤（AF）引起心悸而来我们部门就诊。已安排导管消融治疗房颤。术前多排计算机断层扫描显示下肺静脉（PV）是常见的主干，左、右上肺静脉从左心房顶部中心分支。此外,房颤消融术前对左心房的标测显示下肺静脉或公共干均无潜在可能。我们进行了左右上PV和后壁隔离。消融后,起搏器记录中未观察到房颤。
