Which condition is least likely to cause T wave inversion?

• A. Acute coronary syndrome
• B. Electrolyte imbalance
• C. Hypoxia
• D. Atrial flutter

Answer: (D)

T wave inversion on an ECG can signify a variety of cardiac conditions, often reflecting underlying issues with myocardial ischemia, electrolyte disturbances, or other physiological stresses. However, when considering the specific contexts in which T wave inversion typically appears, atrial flutter is less commonly associated with this change compared to the other listed conditions. Acute coronary syndrome is characterized by a spectrum of conditions that impede blood flow to the heart. T wave inversion is commonly seen in situations of myocardial ischemia, making it a strong indicator in these cases. Electrolyte imbalances, such as changes in potassium or calcium levels, can disrupt normal cardiac depolarization and repolarization processes, leading to T wave alterations, including inversion. Hypoxia also affects the heart’s electrical activity by creating an imbalance in oxygen delivery, which can similarly result in T wave changes. In contrast, atrial flutter primarily involves an irregular atrial rhythm that may affect the heart rate, but it does not inherently disrupt the ventricular repolarization process in a way that leads to T wave inversion. Thus, while it can present with other ECG changes, T wave inversion is not a hallmark of atrial flutter, making it the least likely condition to cause this specific finding on an ECG.
