Define heart attack and infarct. How does atherosclerotic plaque affect the heart? 12. Explain how cardiac muscle cells in the SA node produce action potentials spontaneously and why the SA node is the heart’s pacemaker. 13. What is the function of the conduction system of the heart? Starting with the SA node, describe the route of an action potential as it goes through the conduction system of the heart
