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.
