In this article, the authors outline the key components behind the automated generation of the cardiac impulses and the effect these impulses have on cardiac myocytes. Also, a description of the key components of the normal cardiac conduction system is provided, including the sinoatrial node, the atrioventricular node, the His bundle ...
WebFrom the perspective of a pacemaker, it is a real-time system requiring precise timing of electrical signals. The cardiac conduction system is a network of nodes and pathways carrying electrical signals that cause the chambers in the heart to contract and relax (Figure 1). In a healthy heart, contractions happen in rhythm.
