Conduction System Part I The cardiac conduction system is a highly specialized network of modified cardiac muscle fibers that generates and transmits electrical impulses, ensuring the heart beats in a coordinated and efficient manner. This process begins at the sinoatrial (SA) node, located in the right atrium near the opening of the superior vena cava. The SA node acts as the natural pacemaker of the heart, initiating impulses at a normal intrinsic rate of 60–100 beats per minute and setting th
