Axis,tricular repolarization (T waves). Axis is not a vector—axis only has direction, while a vector has both direction and amplitude. The normal direction of all the axes is inferior and left, between 0° and +90°. Changes in the direction of each axis can be meaningful in identifying the presence or progression of cardiac diseases in patients.
