What does an inverted T wave potentially indicate?

• A. Atrial hypertrophy
• B. Myocardial ischemia or infarction
• C. Ventricular tachycardia
• D. Normal physiological response

Answer: (B)

An inverted T wave is often associated with myocardial ischemia or infarction. This change in the T wave morphology can indicate that the heart muscle is not receiving enough blood supply, leading to a lack of oxygen. When ischemia occurs, it affects the repolarization phase of the cardiac cycle, which is represented by the T wave on the ECG. The inversion is considered a significant finding and is commonly evaluated in conjunction with other leads and clinical signs to assess for potential heart problems. While the T wave can show different patterns based on various physiological and pathological conditions, the specific context of inverted T waves being indicative of myocardial ischemia or infarction is particularly important for diagnosing acute coronary events. This makes it a key element in the interpretation of ECGs in patients presenting with symptoms of chest pain or other cardiac-related issues.
