*In electrocardiography, the T wave represents the repolarization of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period or vulnerable period. *the T wave represents the repolarization of the ventricles. ... Repolarization of the ventricle happens in the opposite direction of depolarization and is negative current, signifying the relaxation of the cardiac muscle of the ventricles. ** In general, T wave changes are very non-specific. They can occur with hyperventilation, anxiety, drinking hot or cold beverages, and positional changes. ... Hyperkalemia (hyperpotassemia) can cause tall, peaked T waves. Hypokalemia and ischemia can cause low amplitude or inverted T waves.
