In a 52-year-old man, a spontaneous right tension pneumothorax was associated with transient bradycardia, hypotension and electrocardiogram (ECG) changes consisting of precordial ST elevation suggestive of acute myocardial injury. Immediately after chest tube placement, the ECG reverted to near normal. Serial cardiac enzymes and isoenzymes showed no evidence of myocardial infarction. To our knowledge, this is the first reported case of this association. The ECG changes may be related to the hypotensive state induced by the tension pneumothorax with resulting decreased coronary artery blood flow and myocardial ischemia that resolved without infarction.
在一名52岁男性患者中，自发性右侧张力性气胸伴有短暂性心动过缓、低血压以及心电图（ECG）改变，表现为胸前导联ST段抬高，提示急性心肌损伤。胸腔闭式引流管置入后，心电图立即恢复至接近正常。系列心肌酶和同工酶检查未显示心肌梗死的证据。据我们所知，这是首例报道的这种关联病例。心电图改变可能与张力性气胸所致的低血压状态有关，导致冠状动脉血流减少和心肌缺血，但未发生梗死而得以缓解。
