Summary. The purpose of research is the identification of signs of the left ventricular diastolic dysfunction in adolescents with some forms of the myocardial pathology. Depending on the ratio of the early to late left ventricular filling velocities, 3 types of diastolic dysfunction were established. In the group of adolescents with the cardiac arrhythmias most frequently reported types were pseudonormalization and restrictive diastolic dysfunction, in patients with dysplastic cardiomyopathy a gradual shift from the type of slow relaxation to the restrictive type with an increasing the left atrium diameter and increasing of the pressure in the left parts of the heart were marked. In patients with hypertension not only diastolic but also systolic dysfunction with hypertensive myocardial remodeling of its cavities were formed.
