The normal QRS axis, like the P wave axis, points downward and to the left within a coordinate between -30 o and +90 o. This axis is said to be deviated to the left (left axis deviation or LAD) if it lies between -30 o and -90 o; and deviated to the right (right axis deviation or RAD) if it lies between +90 o and 180 o.
