Abstract:
Author analysed the postexercise electrocardiogram of 139 cases of normal group and 106 cases of cardiovascular disease according to Rhee's criteria, Master's criteria and Lepeschkin's criteria. following results were obtained: 1. 8.7% of normal group was revealed positive by Rhee's criteria of analysis of double Masters'2 step excrcise test, 9.3% by Master's criteria and 27.3% by Lepeschkin's criteria, were as 35.8% of cardiovascular cases was revealed positive by Rhee's criteria, 38.6% by Master's criteria, and 43.3% by Lepeschkin's criteria. 2. Almost the same positive ratio was revealed both when by UP segment of Master and when by O point of Lepeschkin were considered to be the baseline. 3. Determination of QT ratio and the QX/QT fraction had no diagnostic value of ischemic heart disease. 4. No significant relationship was found between abnormal response of exercise electrocardiogram and coronary risk factors. 5. After exercise test, T wave changes were found in few cases, where as U wave changes were found in many cases, but both changes had no diagnostic value of ischemic heart disease.
