Functional diagnostics of hemodynamic processes is the basis of modern medicine. The diseases of cardiovascular system are the main cause of death worldwide now. The study of cardiac output in persons with congenital dysfunction of the auditory analyzer is important, due to the lack of knowledge about the impact of the primary pathology on the development of other body systems during ontogenesis.

Objective. The study of the parameters of cardiac output in young people aged 17-19 years with hearing impairment.

Methods. Ultrasonic measurement of systolic ejection parameters and determination of other hemodynamic parameters (velocity time integral, stroke work, compliance, and others).

Results. People with hearing impairments as compared with the control groups have higher values ​​of systolic ejection and lower values ​​of compliance indicators.

Conclusions. Sympathicotonia and reduced elastic properties of the arterial system were identified in individuals with hearing impairment in the age group of 17-19 years, regardless of the severity of the pathology.

Key words: cardiovascular system, hemodynamics, ultrasound research methods, cardiac output.
