We present a case of transient abnormal Q-waves (TAQ) and a review of the literature. TAQ are defined as abnormal Q-waves, which disappear within ten days. They are most often seen in patients with ischemic heart disease (IHD) but are also seen in other conditions. Brief episodes of myocardial ischemia giving rise to reversible biochemical and ultrastructural myocardial changes, resulting in transient ECG changes, provide an accepted theory for the pathogenesis of TAO. Investigations have shown that the occurrence of exercise-induced TAQ may be a symptom of IHD. It is impossible to distinguish TAQ from Q-waves induced by myocardial infarction. Appearance of TAQ during exercise-testing frequently indicates IHD.
我们报告一例短暂异常Q波（TAQ）病例并对文献进行综述。TAQ被定义为在十天内消失的异常Q波。它们最常见于缺血性心脏病（IHD）患者，但也可见于其他情况。短暂的心肌缺血发作导致可逆的生化和超微结构心肌改变，进而引起短暂的心电图变化，这为TAQ的发病机制提供了一种被认可的理论。研究表明，运动诱发的TAQ的出现可能是IHD的一种症状。无法将TAQ与心肌梗死诱发的Q波区分开来。运动试验期间TAQ的出现常常提示IHD。
