The preferred terminology is: "…Myocardial infarction of indeterminate duration". A finding of "septal infarct, age undetermined," on an electrocardiogram means the patient may have suffered a myocardial infarction, more commonly known as a heart attack, at some undetermined time in the past, according to the Clinical Exercise Physiology Consortium.
