The main electrical forces of the QRS ventricular wave go in a leftward and downward direction when looking at the body face on. The measurement of angle of this direction, projected to the frontal plane, is useful because it may change with age and with size and condition of the heart muscle. If the detailed axis, as described in Chap. 12, is not measured, axis patterns are coded.
