TY - CHAP M1 - Book, Section TI - The Heart Pump A1 - Mohrman, David E. A1 - Heller, Lois Jane Y1 - 2018 N1 - T2 - Cardiovascular Physiology, 9e AB - The student knows the basic electrical and mechanical events of the cardiac cycle:Correlates the electrocardiographic events with the mechanical events during the cardiac cycle.Lists the major distinct phases of the cardiac cycle as delineated by valve opening and closure.Describes the pressure and volume changes in the atria, the ventricles, and the aorta during each phase of the cardiac cycle.Defines and states normal values for (1) ventricular end-diastolic volume, end-systolic volume, stroke volume, diastolic pressure, and peak systolic pressure, and (2) aortic diastolic pressure, systolic pressure, and pulse pressure.States similarities and differences between mechanical events in the left and right heart pumps.States the origin of the heart sounds.Diagrams the relationship between left ventricular pressure and volume during the cardiac cycle.The student understands the factors that determine cardiac output:Defines cardiac output.States the relationship between cardiac output, the heart rate, and stroke volume.Identifies the major determinants of stroke volume.States the Frank–Starling law of the heart.Predicts the effect of altered ventricular preload on stroke volume and the ventricular pressure–volume relationship.Predicts the effect of altered ventricular afterload on stroke volume and the ventricular pressure–volume relationship.Predicts the effect of altered ventricular contractility (inotropic state) on stroke volume, ejection fraction, and the ventricular pressure–volume relationship.Draws a family of cardiac function curves describing the relationship between filling pressure and cardiac output under various levels of sympathetic tone.The student understands the sources of energy and the energy costs of cardiac work:Identifies the cardiac substrates and metabolic pathways for ATP production.Lists the factors that influence myocardial oxygen consumption.
