Top best answers to the question «What does t wave inversion indicate»

The T wave represents ventricular repolarization, and its direction is normally the same as the major deflection of the QRS complex that precedes it. 2 T-wave inversion may indicate myocardial ischemia and may also precede the development of ST-segment elevation.

  • Abnormal ECGS: T wave inversions are an abnormal electrical pattern on an ECG which can indicate a heart problem. Most serious would be an indication of ischemia, or lack of blood flow to a part of the heart muscle. This occurs when there are cholesterol blockages in the coronary arteries.

Inverted T wave is considered abnormal if inversion is deeper than 1.0 mm. Inverted T waves found in leads other than the V1 to V4 leads is associated with increased cardiac deaths. Inverted T waves associated with cardiac signs and symptoms (chest pain and cardiac murmur) are highly suggestive of myocardial ischaemia.

  • To clarify, isolated T-wave inversions indicate that there has been ischemia. Ischemic T-wave inversions are symmetric (the normal T-wave is asymmetric) and maybe, but rarely are, deeper than 10 mm. ECG leads with the opposite angles of observation (opposite to leads with T-wave inversions) usually display positive T-waves.
