Beschreibungen/Notizen

• We have studied in different forms of heart disease an index of myocardial oxygenation (Io) expressed by the correlation between the availability and consumption of oxygen by the myocardium. Its variations in comparison with electrocardiographic changes are analyzed. From a hemodynamic point of view (with coronary arteries presumably within normal limits), the normal oxygenation index is not followed by electrocardiographic changes while a low index (hypoxia) is represented by T wave, S-T and QRS changes. It is apparent that organic changes of the coronary arteries, which are frequently associated with the hemodynamic disturbances, would modify these conclusions. The importance of the vascular factor can be estimated through the possible electrocardiographic changes in cases with no alteration or slight alteration of the index of myocardial oxygenation.
