T wave inversion is most commonly a sign of which condition?

• A. Recent myocardial infarction
• B. Cardiac arrest
• C. Stable angina
• D. Heart failure

Answer: (A)

T wave inversion is most commonly associated with recent myocardial infarction (MI). This change in the T wave is an important finding on the ECG that can indicate underlying myocardial ischemia or injury. During a myocardial infarction, the myocardium (heart muscle) becomes ischemic due to inadequate blood supply. As a result, changes in repolarization occur, which are reflected on the ECG as T wave inversions. Specifically, T wave inversion in the affected leads can provide valuable diagnostic information, helping healthcare providers to identify the area of the heart that is injured or at risk. Other conditions, such as cardiac arrest, stable angina, and heart failure, can also present with ECG changes, but T wave inversion is particularly characteristic of recent myocardial infarctions. In stable angina, for instance, while ischemic episodes can occur, the T waves often revert to their normal appearance between episodes, and significant persistent changes like T wave inversion are not typical. Understanding this relationship helps clinicians narrow down potential diagnoses during patient evaluation.
