Electrical Conduction of the Heart - SA, AV, Bundle of His, R & L BB, Purkinje Fibers

Hello world! Here is a brief summary of the video: SA node: -Natural pacemaker of the heart -Located in upper portion of the right atrium -Responsible for depolarization (contraction) of atria -Connects to Bachmann's bundle via intranodal atrial pathways -Maintains HR of 60-100 BPM AV Node: -Connects electrical impulses from the atria to the ventricles -Impulses from the atria must pass through the AV node before they reach the ventricles -Located in the base of the right atrium -If SA fails, AV will maintain HR of 40-60 BPM Bundle of His -Located in the inter-ventricular septum -Carry impulses to the ventricles -Break-up into the right & left Bundle branches R & L bundle Branches: -Right bundle branch carries impulses to the right ventricle -Left bundle branch carries impulses to the left ventricle -Break-up into smaller fibers known as Purkinje Fibers Purkinje Fibers: -Small fibers located throughout the ventricles -These fibers carry electrical impulses to the ventricles so a synchronous contraction can occur If SA & AV node fail, Purkinje Fiber will generate a HR of less than 40BPM.
