An ST segment elevation myocardial infarction (STEMI) that produces anterior ST segment elevation (STE) is typically caused by acute occlusion of the left anterior descending (LAD) artery. Anterior STE, however, may also be caused by acute occlusion of either the proximal right coronary artery (RCA) or the right ventricular marginal branch (RVB). It has been thought that, in contrast to occlusions of the LAD, proximal RCA/RVB occlusion rarely causes Q waves in the right precordial leads. We present a case where a proximal RCA occlusion produced not only anterior STE, but also anterior T wave inversions and anterior Q waves.
产生前壁ST段抬高(STE)的ST段抬高型心肌梗死(STEMI)通常由左前降支(LAD)动脉急性闭塞引起。然而,前壁STE也可能由近端右冠状动脉(RCA)或右心室边缘支(RVB)急性闭塞引起。与LAD闭塞不同,人们一直认为近端RCA/RVB闭塞很少导致右胸前导联出现Q波。我们报告一例近端RCA闭塞不仅导致前壁STE,还导致前壁T波倒置和前壁Q波的病例。
