[Character of central hemodynamics in hypotensive type autonomic vascular dysfunction in juveniles].

With an aid of an ultrasound investigation of the heart, aspects of central hemodynamics in 408 juveniles ranging in age between 11 to 14 years have been studied. Of these, 339 were diagnosed as having hypotensive type vegetovascular dysfunction, the other 69 essentially healthy juveniles formed a control group signs of systolic and diastolic dysfunction of the myocardium of the left ventricle revealed in the patients with hypotensive type vegetovascular dysfunction. Systolic dysfunction was compensated by increase in the rate of the heart's beat. Compensation of diastolic dysfunction was achieved by increase in contractility of the muscle of the left ventricle.
