In order to evaluate the validity of usefulness of commercially available automated exercise ECG analyses systems, 107 patients were studied. Results of automated analysis, visual analysis and coronary arteriography were correlated. Automated analysis was shown to be valid and useful. ST integrals recorded post exercise appeared superior to those recorded during exercise for a higher specificity and predictive value. ST integrals recorded during exercise were more sensitive than post exercise ST integrals. Using post exercise ST integrals it was possible to distinguish between mild and severe disease. Automated measurement of during and post exercise integrals permits the physician to choose a cut off integral for normality which will provide him with the sensitivity and specificity which best suits his purpose.
