Final answer:
Post myocardial infarction (MI), there are several permanent EKG changes that can be observed, such as an enlarged Q wave, elevated ST segments, and inverted T waves. These changes indicate damage to the cardiac muscle and ongoing ischemia.
Step-by-step explanation:
Post myocardial infarction (MI), there are several permanent EKG changes that can be observed. One of the most common changes is an enlarged Q wave, which indicates damage to the cardiac muscle. Other changes include elevated ST segments and inverted T waves. These changes are indicative of ongoing ischemia or lack of oxygen supply to the myocardium.
