We report a patient who presented with new onset atrial fibrillation in the setting of inferior ST-segment elevation myocardial infarction (STEMI). Cardiac catheterization revealed proximal occlusion of the left circumflex artery. Balloon angioplasty and stenting restored flow to a large left atrial branch, with prompt conversion of the rhythm to atrial flutter, and then to sinus rhythm. To our knowledge this represents the first demonstration of restoration of sinus rhythm by reversing left atrial ischemia in the setting of STEMI.
我们报告了 1 例新出现的心房颤动患者，其在急性下壁 ST 段抬高型心肌梗死（STEMI）的情况下出现。冠状动脉造影显示左回旋支近端闭塞。球囊血管成形术和支架置入术恢复了左心房大分支的血流，节律迅速转为房扑，然后转为窦性心律。据我们所知，这代表了首例在 STEMI 情况下通过逆转左心房缺血恢复窦性心律的证明。
