Presentation Transcript

  1. NURS 315/501 Bootcamp Lecture: Disorders of cardiac function

  2. Perfusion of the Heart • Describe how is the myocardium supplied with oxygen. • Discuss the factors that regulate blood flow to the myocardium. • Volume, pressure, resistance, and flow

  3. Cardiac Conduction System • Describe the cardiac conduction system. • SA node, AV node, Bundle of His, bundle branches, Purkinje fibers

  4. Coronary Perfusion and Electrical Activity • Describe the 3 phases of the action potential. • Resting membrane potential • Depolarization • Repolarization • Correlate the ECG events with the mechanical events of a cardiac cycle.

  5. Phases of the Action Potential • Describe the 5 phases of a cardiac action potential. • Phase 4 • Phase 0 • Phase 1 • Phase 2 • Phase 3

  6. Coronary Heart Disease • Describe the pathogenesis of CAD. • Discuss how does atherosclerosis in coronary arteries can lead to ischemia, injury, and infarction. • Compare and contrast ischemia, injury, and infarction. • Describe the pathologic changes associated with MI.

  7. Coronary Heart Disease • Schematically represent the 2 types of coronary heart disease.

  8. Coronary Heart Disease • Acute Coronary Syndrome: • Define unstable angina • Describe changes in ECG and serum markers during a NSTEMI vs. STEMI. • What does abnormal Q-waves in a 12-lead ECG mean?

  9. Coronary Heart Disease • Chronic Ischemic Disease. • Compare and contrast stable angina, variant/vasospastic angina, and silent myocardial infarction.

  10. Coronary Heart Disease • Identify the goals for the management of angina, CHD, and AMI. • Describe the management strategies utilized to achieve management goals. • Anti-anginal drugs • Anti-platelet therapy • Anticoagulant therapy

  11. Heart Failure • Describe the common causes of heart failure. • Describe the cycle through which compensatory mechanisms lead to heart failure and how is the cycle perpetuated. • Describe the compensatory mechanisms involved in the physiologic response to decreased cardiac output.

  12. Heart Failure • Distinguish between systolic and diastolic heart failure. • Distinguish between right and left sided heart failure. • Identify the goals of HF management.

  13. Heart Failure • Describe the role of diuretics in the management of HF • Describe how ACE-I and ARB’s achieve the goals for HF management. • Describe the function of beta-blockers in the management of HF. • Describe the function of digoxin in the management of HF. • What role does calcium channel blockers play in the management of HF?

  14. Disorders of Valve Function • Compare and contrast the following disorders of valve function: • Mitral stenosis • Mitral regurgitation • Aortic stenosis • Aortic regurgitation

  15. Compare and contrast the following sinus dysrhythmias; Normal sinus rhythm Sinus bradycardia Sinus tachycardia Sinus dysrhythmia Compare and contrast the following atrial dysrhythmias: Premature atrial contraction Atrial flutter Atrial fibrillation Disorders of cardiac electrical conduction

  16. Compare and contrast the following ventricular dysrhythmias: Premature ventricular contraction Ventricular tachycardia Ventricular fibrillation Compare and contrast the following atrio-ventricular conduction dysrhythmias: 1st degree AV block 2nd degree AV block 3rd degree AV block Disorders of cardiac electrical conduction

  17. Disorders of cardiac electrical conduction • Outline in a table: • The four classes of anti-dysrhythmic drugs, • Agents classified under the class, • Their mechanism of action, • Indications, • Adverse effects, • Special considerations.

  18. Shock • Define shock • Name an important serum marker used to assess cellular aerobic metabolism in tissues. • Identify SNS compensatory mechanisms to ensure adequate tissue oxygenation.

  19. Shock • Compare and contrast the 4 types of circulatory shock. • Name common complications of shock on organ systems.

  20. Shock • What is the ultimate goal of therapy in management of shock? • Identify mechanisms to ensure adequate oxygen delivery during shock.
