An 18-year-old man presented with a spontaneous right pneumothorax. An initial electrocardiogram (ECG) showed an S wave in lead I, a Q wave in lead III, and an inverted T wave in lead III. This ECG pattern, S1Q3T3, has been most often associated with pulmonary embolus. These changes resolved with partial reexpansion of the lung. Both right and left pneumothorax have been associated with ECG changes, including changes that mimic myocardial ischemia. Because the clinical presentation of pneumothorax may be similar to angina or pulmonary embolus, ECG changes with pneumothorax may lead to confusion in the diagnosis.
一名18岁男性因自发性右侧气胸就诊。初始心电图（ECG）显示I导联有S波，III导联有Q波，III导联T波倒置。这种ECG模式，即S1Q3T3，最常与肺栓塞相关。随着肺部分复张，这些变化得以缓解。右侧和左侧气胸均与ECG改变有关，包括类似心肌缺血的改变。由于气胸的临床表现可能与心绞痛或肺栓塞相似，气胸时的ECG改变可能会导致诊断混淆。
