AGE AND SEX DINAMICS OF HEART STRUCTURAL PARAMRTERS IN SCHOOLCHILDREN OF THE CIRCUMPOLAR REGION
The results of the study of the structural parameters of heart healthy children 7-17 years old living in the Circumpolar region of Russia, according to sex and age. To assess the state of the main indicators of the heart used the method of transthoracic echocardiography. Cardiac ultrasound was performed according to standard procedures for echocardiography Aloka Alpha 7 ProSound. The results showed that the basic linear parameters of the heart of the European North of boys was significantly increased at 9 and 13 years, the girls - to 8 and 12 years, thus revealed that some of the structural parameters of the heart boys dominate the performance of girls as early as 7 years old. Thus, these changes suggest that, most likely, growth jumps in girls and boys are at different ages, which is supported by the literature.
