Interval. Ventricular deploariztion begin with septum
V 6
septum depolarize from left It also produce the corresponding
to right by LBB .in this figure small initial q in V6 . As direction is
represented by arrow . The away from lead
septal vector results in the V 6
small initial r wave in V1
As its direction toward V 1
