Guided Lecture Notes, Chapter 24, Disorders of Cardiac Function Learning Objective 1. Characterize the function of the pericardium. Describe to the students the general anatomy of the pericardial sac and list its functions. of the positioning of the pericardium. (Refer Use “fist in a water balloon” as an example to PowerPoint slide 2.) Learning Objective 2. Compare the clinical manifestations of acute pericarditis and chronic pericarditis. Describe the manifestations of acute versus chronic disease process. Emphasize the immediacy of the acute onset versus the silence of the chronic presentation. (Refer to PowerPoint slides 3 to 5.) Learning Objective 3. Describe the physiologic impact of pleural effusion on cardiac function and relate it to the life-threatening nature of cardiac tamponade. Explain how the effusion puts pressure on the heart and restricts the contractile ability, but does not affect the electrical activity. It results in pulse electrical activity. (Refer to PowerPoint slides 5 and 6.) Describe blood flow in the coronary circulation and relate it to the Learning Objective 4. determinants of myocardial oxygen supply and demand. Describe the anatomy of coronary vessel arrangement, emphasizing the points on the heart where each artery feeds the muscle. Relate this to the site of blockage as the determinate of tissue damage. (Refer to PowerPoint slides 7 to 10.) Define the term and distinguish among chronic Learning Objective 5. acute coronary syndrome stable angina, unstable angina, non–ST-segment elevation myocardial infarction, and elevation myocardial infarction in terms of pathology, symptomatology, ECG changes, and serum cardiac markers. Briefly review the normal physiology of ECG. Base the lecture discussion on what the ECG shows the clinician and then what abnormalities can demonstrate. Then, correlate
