The article presents the results of the survey 98 term newborns aged 5-12 days who had cerebral ischaemia, in comparison with the control group which consists of 32 healthy children at the similar age. There are anamnestic, clinical, neurophysiological characteristics of the patients in the test group. Every child had a comprehensive study of the cardiovascular system, including electrocardiography, Holter monitoring of the heart rate, cardiospacegraphy. The electrophysiological parameters of cardiac activity were analysed and the following results were obtained: there was an increase in the heart rate at nigh, we also could notice the reduction in the heart rate variability and some changes in the structure of the wave parameters, that indicated the strong influence of the sympathetic division of the autonomic nervous system on the heart rate regulation. These changes were more pronounced in children who had cerebral ischaemia than in healthy newborns. Moreover, the patients in the test group had recorded rhythm and conduction disturbances more frequently than healthy children.

Key words: cerebral ischaemia, Holter monitoring, cardiospacegraphy, autonomic nervous system.
