The AV node gives rise to the conducting bundle of the heart, AV bundle (bundle of His). The AV bundle divides and forms the right & left bundle branches. The terminal branches of the bundle branches are the Purkinje fibers. The more gap junctions, the faster the action potential spreads! Total time = ~370ms

Ex. -- On the ECG overhead, there is an R, R1, S pattern…This can occur due to a bifascicular bundle branch block. The RPBBB (right posterior bundle branch block) and LPFBB (left posterior fascicular bundle block) are the cause of the block. In a 1st degree AV block, there is an increased distance between the P and the QRS wave.
