What does a flat T wave potentially indicate?

A flat T wave can signify myocardial ischemia, which is a condition where there is reduced blood flow to the heart muscle. This reduction in blood supply can lead to oxygen deprivation of the cardiac tissues. As the heart's electrical activity is altered in response to ischemia, the shape and characteristics of the T wave on an electrocardiogram (EKG) may change, often manifesting as a flatter appearance.

In addition to ischemia, other conditions can influence T wave morphology, but in the context of this question, recognizing the connection between a flat T wave and myocardial ischemia is crucial because it indicates underlying heart health concerns that may require investigation and intervention. Proper identification of these EKG changes assists healthcare professionals in diagnosing and managing potential cardiac issues effectively.
