  • Title: Exercise stress testing for the family physician: Part II. Interpretation of the results.
    Author: Evans CH, Karunaratne HB.
    Journal: Am Fam Physician; 1992 Feb; 45(2):679-88. PubMed ID: 1739052.
    Abstract:
    Information gained from exercise stress testing includes the heart rate and blood pressure response, the presence of symptoms or dysrhythmias, functional aerobic capacity and evidence of myocardial ischemia. Certain ST-segment patterns correlate with various degrees of ischemia. Overall, stress testing has a sensitivity and a specificity of about 70 and 75 percent, respectively, but the results are even more useful than this when considered in light of the pre- and post-test probability of coronary artery disease. Use of the exercise test score and decision-tree algorithms is helpful in clinical decision making.
