The point of view is stressed that the electrocardiogram must be interpreted in terms of whether its appearance is fixed or changing. A limited number of serial electrocardiograms generally permits decision regarding the reversibility or nonreversibility of the electrocardiographic alterations. Two case histories illustrate the occasional disappearance of characteristic electrocardiographic changes of myocardial infarction. It is emphasized that the electrocardiogram as such is not generally helpful in demonstrating the extension of an acute myocardial infarct and that once a diagnosis of acute infarction has been settled on the basis of dynamic sequential changes, there is no good reason for indiscriminate repetition of the electrocardiogram.
