Which of the following EKG changes is commonly observed during a myocardial infarction?

Peaked T waves are a common EKG change observed during a myocardial infarction, particularly in the acute stage, especially when there is significant myocardial ischemia. These changes indicate a disruption in the repolarization of cardiac myocytes as a result of altered electrical activity and metabolic processes during ischemia. The peaked T waves can indicate hyperacute changes reflecting the early phase of an infarction and are often associated with the onset of chest pain and other ischemic symptoms.

In myocardial infarction, the changes in the EKG can progress to include ST elevation, which is a hallmark for diagnosing an ST-Elevation Myocardial Infarction (STEMI). Detecting peaked T waves early can help in timely diagnosis and intervention, making them a significant EKG alteration to recognize.

Flat T waves and U waves are less characteristic of myocardial infarction. Flat T waves can indicate electrolyte imbalances or chronic conditions but do not specifically signal acute ischemia. U waves are often associated with conditions like hypokalemia and are not directly related to myocardial infarction. Bradycardia, while it can occur in several cardiac conditions, is not a direct EKG change associated specifically with myocardial infarction compared to steep T wave changes. Therefore, recognizing peaked T
