The phrase bundle branches refers to the three branches of the bundle of His, a grouping of heart muscle cells which are responsible for transmitting the electrical impulses from the heart's AV node to the top of its fascicular branches; in turn, this transmits the electrical impulses to the heart's Purkinje fibers, which lead to the regular contraction of the cardiac muscles in the left and right ventricles.
