What is the significance of an inverted T wave on the EKG?

An inverted T wave on an electrocardiogram (EKG) is significant as it may indicate ischemia or myocardial injury. The T wave represents repolarization of the ventricles, and when it is inverted, it can suggest that there is a disturbance in the electrical activity of the heart muscle, often due to insufficient blood flow (ischemia). This finding may occur in a variety of conditions, including acute myocardial infarction (heart attack), where part of the heart muscle is damaged due to a lack of oxygen.

While other heart conditions may present with different EKG findings, an inverted T wave is particularly associated with the heart being under stress or injured. In the context of a clinical assessment, the presence of an inverted T wave can alert healthcare professionals to consider further investigation and management of potential underlying cardiac issues.
