They play an integral role in the electrical conduction system of the heart by transmitting cardiac action potentials from the bundle of His to the Purkinje fibers. This particular electrocardiogram supports that not all bundle branch blocks are due to a diseased conduction system but they may also be caused by a concealed retrograde penetration from the contralateral bundle preventing anterograde conduction through a particular bundle resulting in what is known as a functional block.
