Compare and contrast cardiac and skeletal muscle in terms of electrical stimulus and action potentials (excitation-contraction coupling), role of calcium, energy use and production, and ways to develop increased force of contraction. How does the vulnerability of the myocardium relate to the fact that heart disease is the leading cause of death?
