title: [Significance of the changes in initial and terminal segments of the ventricular ECG complex for evaluation of the status of myocardial energy metabolism in patients with mitral valve defects with predominant stenosis].
abstract: The amplitude-time and velocity parameters of QRS complex and T wave were compared with intraoperative values of aerobic and anaerobic myocardial energy metabolism (as shown by left auricle biopsy) in 187 patients with mitral valve disease with predominant stenosis. The ECG elements were demonstrated to be of informative value for the evaluation of myocardial energy metabolism and the clinical condition of the patients. The ratio of descending T wave downsloping to its ascending upsloping rates, as well as the amplitude-time parameter of QRS complex and T wave were demonstrated to be closely related to myocardial energy metabolism.
