What is an inverted T-wave indicative of?

An inverted T-wave on an electrocardiogram (EKG) is primarily indicative of myocardial ischemia. This refers to a reduced blood flow to the heart muscle, which can occur due to conditions such as coronary artery disease. When the heart muscle does not receive sufficient oxygen, changes in the electrical activity can manifest as T-wave inversions. This is often seen in patients experiencing angina, myocardial infarction, or other forms of cardiac distress related to inadequate blood supply.

Inverted T-waves can also occur in other specific conditions, but their strongest association is with ischemic changes. Understanding the clinical significance of T-wave inversions can help healthcare providers identify and manage patients experiencing cardiac events more effectively.
