title: [Classification of acquired aortic stenosis (based on electrocardiographic study data)].
abstract: The article is based on the case records of 192 patients with acquired aortic stenosis and interpretation of the ECG of 187 patients. In this group, 143 patients underwent operation and 8 died in the period of their examination. The purpose of the examination consisted in determining whether or not the ECG could characterize the stage of the cardiac disease. Four types of electrocardiographic changes of the ventricular complex characteristic of left-ventricular hypertrophy were distinguished. On comparing clinical and electrocardiographic findings, no clear dependence was revealed between the clinical manifestations of the stenosis and the severity of the hypertrophic process in the muscle of the left ventricle according to the ECG data. The information gained by means of ECG is confirmed by the results of pathomorphological examination. The authors suggest a clinical classification of acquired aortic stenosis based on the function changes in the left-ventricular myocardium as determined from the ECG.
