5 Written questions

5 Multiple choice questions

  1. - treadmill
    - leg ergometer
    - arm ergometer
  2. 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. - greatest when pre-test likelihood is intermediate to high probability of CAD
    - Little value in testing individuals who are asymptomatic
  4. 1) Determine # of ppl in population w/ disease
    2) Determine # w/ disease that will have '+' testing (# w/ disease x 0.7)
    3) Determine # w/ disease that will have '-' test (Total diseased # - # w/ '+' test)
    4) Do the same for those w/o disease
  5. - Positive Predictive Value = True Positive/(TP + false positive)
    - Negative Predictive Value = True Negative/ (TF + False Negative)

5 True/False questions

    - leg ergometer
    - arm ergometer

          

  2. List some relative contraindications to exercise- unstable angina
    - acute infection
    - uncontrolled arrhythmia

          

  3. List some indicators for stopping an ETT.- treadmill

  5. Describe the sensitivity, specificity of exercise testing diagnostics with ECG. What is a better method?- Sensitivity = 70% (7 of 10 patients w/ CAD will have '+' test)
    - Specificity = 90% (9 of 10 patients w/o CAD will have '-' test)
