Popis: Gorrelations of the metabolic state of human heart to EGG and to Xray findings were studied and discussed.There was a significant decrease in myocardial citrate extraction and a tendency of disturbed lactate and pyruvate metabolism in the cases with ST-T changes. In many cases with ST-T abnormalities, myocardial oxygen extraction coefficient was increased.QTc correlated, in general, with oxygen extraction coefficient. The magni-tude of G in frontal plane showed slight but significant negative correlation with oxygen extraction coefficient.Oxygen extraction coefficient increased distinctly with the enlargement of the heart in cases with valvular disease, while it was not so apparent in patients with hypertensive and/or sclerotic heart disease without failure.In cases with cardiac enlargement due to valvular disease of the heart, ST-T abnormalities, increase in QTc and reduction of the magnitude of G were frequently observed.
