As a medical professional with expertise in cardiology, I can explain that an inverted T wave on an electrocardiogram (ECG) can have various meanings and is not always indicative of a serious condition. Here's a breakdown of what it might mean: 1. Coronary Ischemia: This is a lack of blood flow to the heart muscle, which can be due to a blockage or narrowing of the coronary arteries. Inverted T waves can be a sign of this condition, particularly in specific leads on the ECG. 2. Wellens' Syndrome: This is a specific type of coronary ischemia that affects the left anterior descending artery. It is characterized by deep and symmetrical T wave inversions in the anterior leads of the ECG. 3. Left Ventricular Hypertrophy (LVH): This is a condition where the heart's main pumping chamber becomes thicker. In some cases, LVH can cause T wave inversions, particularly in the lateral leads of the ECG. 4. CNS Disorder: In rare cases, T wave inversions can be associated with central nervous system (CNS) disorders, although this is not a common occurrence. 5. Pediatric Inverted T Waves: In children, T wave inversions are commonly seen in the right precordial leads and are usually benign. They reflect a more dominant right ventricular force and are not harmful. It's important to note that the interpretation of T wave inversions requires a comprehensive evaluation that includes the patient's symptoms, medical history, and a thorough review of the ECG by a healthcare professional. An isolated finding of inverted T waves may not be significant, but it should always be evaluated in the context of the patient's overall clinical presentation. read more >>

T-wave inversion (negative T waves) can be a sign of coronary ischemia, Wellens' syndrome, left ventricular hypertrophy, or CNS disorder. Pediatric inverted T waves: normally found in the right precordial leads. They are not harmful and signify more dominant right ventricle force.read more >>
