Document Summary

Test will be over the last few slides of chapter 8; all of chapters 9 and 10; first few slides of chapter 11. The myocardium is composed of three layers: (1) epicardium (outer layer); (2) myocardium (middle layer composed of cardiac muscle fibers); and endocardium (inner layer). The contraction phase of the cardiac cycle is called systole and the relaxation period is called diastole. The average blood pressure during a cardiac cycle is called mean arterial pressure. Blood pressure can be increased by one or all of the following factors: A recording of the electrical activity of the heart during the cardiac cycle is called the electrocardiogram (ecg). Cardiac output is the product of heart rate and stroke volume (q = hr x sv). Figure 9. 18 summarizes those variables that influence cardiac output during exercise. The pacemaker of the heart is the sa node.
