Elements of cardiac conduction system
WebCardiac conduction can be influenced by various factors including exercise, temperature, and endocrine system hormones. The first step of cardiac conduction is impulse generation. The sinoatrial (SA) node (also referred to as the pacemaker of the heart) contracts, generating nerve impulses that travel throughout the heart wall. WebMay 8, 2024 · This group of muscle cells is called the cardiac conduction system. The main parts of the system are the SA node, AV node, bundle of HIS, bundle branches, and Purkinje fibers. Let's follow a signal through the contraction process. The SA node starts the sequence by causing the atrial muscles to contract.
