The authors compared the electrical activity of the heart with results of echocardiography during rest and during bicycle ergometry in 240 patients with ischemic heart disease, 60 patients with hypertensive disease and in 16 healthy persons. In some of the patients coronarography was carried out. It was established that the informative value of electrocardiography in assessment of the anatomo-functional state of the left ventricle depended on the contingent of the examined patients and reduces as disorders of the functional state of the myocardium tended to advance. The specificity and sensitivity of the electrocardiographic signs of left ventricular hypertrophy reduced in disturbances of ventricular conduction, presence of myocardial infarction in the anamnesis, increase of involvement of the cardiac arteries.
