CLINICAL AND FUNCTIONAL CHARACTERISTICS OF THE CARDIOVASCULAR SYSTEM IN CHILDREN WITH DIFFERENT ADAPTATION CONDITIONS

Abstract

This study examines the clinical and functional characteristics of the cardiovascular system in children living under different adaptation conditions, including high-altitude, industrial urban, and rural environments. A total of 180 children aged 7 to 15 years were examined using clinical, electrocardiographic, echocardiographic, and heart rate variability analyses. The findings revealed significant differences in cardiovascular regulation depending on environmental and psychosocial stressors. Children living at high altitudes and in urban environments exhibited higher heart rates, elevated systolic blood pressure, and decreased heart rate variability compared to those from rural regions. The study highlights that adaptation to environmental and social factors significantly affects the functional state of the cardiovascular system in childhood. Early identification of maladaptive cardiovascular responses is essential for preventive interventions in pediatric health care.
