5 True/False Questions

  1. List some absolute contraindications to exercise- chronic infectious disease
    - uncontrolled metabolic disease
    - hypertrophic cardiomyopathy

          

  2. Describe the sensitivity, specificity of exercise testing diagnostics with ECG. What is a better method?1) Sensitivity - % of persons test who have CAD and show positive test
    2) Specificity - % of persons test that don't have CAD and show negative test
    3) Predictive Value - how accurately a test result correctly identifies a presence or absence of CAD
    4) Positive predication value - % of subjects w/ a positive test that have CAD
    5) Negative predicted value - % subjects w/ negative who don't have CAD

          

  3. List some exercise test and describe who they're appropriate for- chronic infectious disease
    - uncontrolled metabolic disease
    - hypertrophic cardiomyopathy

          

  4. What's the difference b/t absolute and relative contraindications for exercise testing?- chronic infectious disease
    - uncontrolled metabolic disease
    - hypertrophic cardiomyopathy

          

  5. When would you find value in doing a CAD diagnostic test?- greatest when pre-test likelihood is intermediate to high probability of CAD
    - Little value in testing individuals who are asymptomatic
