Abstract
Assessment of the state of the cardiovascular system of children born with intrauterine growth restriction (IGR) compared to children without IGR in given in the article in the neonatal period dynamics. Children born with IGR in the early neonatal period decrease of the amplitude of the P-wave, atrioventricular conductivity acceleration, decrease of the amplitude of the Т -wave, mitral valve anterior cusp flexure in children born with IGR more often than in Diastoilic and systolic diametres of the left ventricle were decreased in children born with IGR, shortening fraction and ejection fraction of the left ventricle were increased compared to children born without IGR (lower than in healthy newborns). Stroke volume, cardiac output and thickness of the posterior wall of the left ventricle were decreased while thickness of the inter-ventricular septum was increased. T ransmittal bloodstream speed was characterized by a decrease in the E peak value and A peak value, which are comparable. Speed of transtricuspid bloodstream expressed by E peak was decreased, while A peak prevailed. T ransaortic bloodstream speed was also decreased. By the end of the neonatal period of life children born with IGR had more expressed sympathetic. Amplitude of P wave increased significantly. Acceleration of atriovantricular conduction persisted, increase of the amplitude of the T wave was registered alongside with decrease of the duration of the Т 1Т interval, shortening of the electrical systole and growth of myocardial metabolism disturbance. In spite of high adaptive and regenerative functions of the heart in newborns with IGR, disturbance of myocardial functions and vegetative regulation providing the basis for pathology are registered.
