The common feature of these 3 case reports can be characterized by the negative symmetric giant T waves developing 1-2 days after an acute myocardial ischemic attack, producing no enzymatic evidence of necrosis, persisting for several days or some weeks. The negative transient T waves are considered to fulfil neither the classical electrocardiographic characteristics of acute or chronic myocardial ischemia nor the criteria of subendocardial necrosis, but are believed to designate the existence of myocardial stunning. The authors suggest, that transient Q waves having been declared as the only electrocardiographic marker of myocardial stunning, reflect severe "transmural stunning" and can be detected relatively rarely, for a short time. In contrast, the transient negative T waves reflect "subendocardial stunning" and can be documented more frequently, persist for a longer time, and therefore could be a simple and sensitive method in detection of myocardial stunning.
这3例病例报告的共同特征表现为急性心肌缺血发作后1-2天出现对称性巨大负向T波,无坏死的酶学证据,持续数天或数周。这种短暂的负向T波既不符合急性或慢性心肌缺血的经典心电图特征,也不符合心内膜下坏死的标准,但被认为提示心肌顿抑的存在。作者指出,短暂Q波曾被宣布为心肌顿抑的唯一心电图标志物,反映严重的“透壁顿抑”,且相对少见,持续时间短。相比之下,短暂负向T波反映“心内膜下顿抑”,出现频率更高,持续时间更长,因此可能是检测心肌顿抑的一种简单而敏感的方法。
