NettetShort after its origin the LBB gives rise to its two main fascicles, anterior and posterior, both heading the anterior and posterior papillary muscles, respectively. The anterior division is thinner and longer than the posterior one. The RBB and the most anterior fibers of the LBB arise at the end of the branching portion. NettetLPO = left posterior oblique; RAO = right anterior oblique. The most impressive feature of the LBB anatomy was its marked variability between individuals. The origin of the LBB is broad in some and narrow in others (ranging from <1 to 14 mm) and is significantly influenced by the anatomical relationship of the His bundle to the IV septum ( 9 , 11 ).
