Describe the incidence, morbidity and mortality of cardiovascular disease. (C-1) Discuss prevention strategies that may reduce the morbidity and mortality of cardiovascular disease. (C-1) Identify the risk factors most predisposing to coronary artery disease. (C-1) Describe the anatomy of the heart, including the position in the thoracic cavity, layers of the heart, chambers of the heart, and location and function of cardiac valves. (C-1) Identify the major structures of the vascular system. (C-1) Identify the factors affecting venous return. (C-1) Identify and define the components of cardiac output. (C-1) Identify phases of the cardiac cycle. (C-1) Identify the arterial blood supply to any given area of the myocardium. (C-1) Compare and contrast the coronary arterial distribution to the major portions of the cardiac conduction system. (C-3) Identify the structure and course of all divisions and subdivisions of the cardiac conduction system. (C-1) Identify and describe how the heart's pacemaking control, rate, and rhythm are determined. (C-2) Explain the physiological basis of conduction delay in the AV node. (C-3) Define the functional properties of cardiac muscle. (C-1) Define the events comprising electrical potential. (C-1) List the most important ions involved in myocardial action potential and their primary function in this process. (C-2) Describe the events involved in the steps from excitation to contraction of cardiac muscle fibers. (C-1) Describe the clinical significance of Starling's law. (C-3) Identify the structures of the autonomic nervous system (ANS). (C-1) Identify the effect of the ANS on heart rate, rhythm and contractility. (C-1) Define and give examples of positive and negative inotropism, chronotropism and dromotropism. (C-2) Discuss the pathophysiology of cardiac disease and injury. (C-1) Identify and describe the details of inspection, auscultation and palpation specific to the cardiovascular system. (C-1) Define pulse deficit, pulsus paradoxus and pulsus alternans. (C-1) Identify the normal characteristics of the point of maximal impulse (PMI). (C-1) Identify and define the heart sounds. (C-1) Relate heart sounds to hemodynamic events in the cardiac cycle. (C-2) Describe the differences between normal and abnormal heart sounds. (C-2) Identify and describe the components of the focused history as it relates to the patient with cardiovascular

compromise. (C-1) 5-2.30 Explain the purpose of ECG monitoring. (C-1) 5-2.31 Describe how ECG wave forms are produced. (C-2) 5-2.32 Correlate the electrophysiological and hemodynamic events occurring throughout the entire cardiac cycle

with the various ECG wave forms, segments and intervals. (C-2) 5-2.33 Identify how heart rates, durations, and amplitudes may be determined from ECG recordings. (C-3) 5-2.34 Relate the cardiac surfaces or areas represented by the ECG leads. (C-2)
