A T-wave is a component of an ECG test. It signifies the repolarization of the heart ventricles after a contraction. In the adjacent image, the T-wave is the hump on the right. Every time your heart beats, the muscle is depolarized by an electrical current that originates in the sinoatrial node of the heart.
The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below). Also, the normal T wave is asymmetric with the first half moving more slowly than the second half. In the normal ECG (see below) the T wave is always upright in leads I, II, V3-6, and always inverted in lead aVR. The other leads are variable depending on the direction of the QRS and the age of the patient.
