Popis:	Aim. To examine the circular and radial deformation of left ventricular in infants, including children born with intrauterine growth retardation (IUGR). Material and methods. The sample of 123 children were examined. 35 children with IUGR were compared with 88 children. The median age was (7,4±3,3) and (7,3±2,4) months, respectively. Using the tissue Doppler examination in Strain Rate Imaging TVI mode speed circular and radial systolic myocardial deformation of the left ventricle were studied at the level of the cross-cut the last echocardiographic short axis. Results and discussion. Were identified two main types of graphs which characterized the deformation rates of myocardial segments. First, a synchronous type, characterized by high-amplitude unidirectional monophasic curves, the second type — asynchronous, combining both positive and negative values of strain rates, which was interpreted as the presence of pronounced systolic
