[Significance of the ECG in the diagnosis of so-called "stunned myocardium"].
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.
