Individual vectors with opposite direction partly cancel each other but as a whole it leads to a resultant
vector. During depolarization of the ventricles the resultant vector will be first oriented as shown in a (top)
and c (bottom). Then, as the last part of the ventricles to depolarize is the base of the left, the resultant vector
will be oriented as shown in b (top) and d (bottom). e and f (bottom) represent ventricular repolarization.
