FEATURES OF HEMODYNAMICS OF PERSONS WITH HEARING LOSS
Abstract. Regular monitoring of the cardiovascular system is necessary not only for individuals predisposed to heart and vascular diseases, but is also of particular importance for persons with congenital diseases of other systems. One of the factors that could affect the normal development of the cardiovascular system may be congenital or early acquired hearing pathology. It should be noted that the age-related physiological characteristics of hemodynamic parameters may differ in individuals with varying degrees of hearing loss. Measurement of hemodynamic parameters in real time in young people with varying degrees of hearing loss in two age groups revealed deviations from the indicators of the control group, as well as between the indicators in different age groups. A number of hemodynamic parameters were analyzed, such as: blood pressure, heart rate, stroke volume, stroke volume index, cardiac output,cardiac index, systemic vascular resistance, systemic vascular resistance index, blood flow integral, ejection time, etc. We obtained significantly higher values of hemodynamic parameters and low values of systemic vascular resistance in
individuals with mild and moderate degree of hearing loss. The effect of arterial stiffness on hemodynamic parameters in patients with severe hearing loss was noted. These studies can be used for medical examinations of students, persons with disabilities; primary admission by a cardiologist of persons with concomitant diseases; functional diagnostics in sports medicine (among professional athletes, amateurs, participants of the Paralympic Games).
