Vegetative regulation of cardiac rhythm in conditions of chronic deficiency in cerebral circulation

The state of autonomic regulation of the heart rate was analyzed in 70 patients according to the variation pulsometry. The patients in focus were diagnosed with disorders of cerebral circulation in vertebrobasilar system due to stenotic lesions of cerebral arteries. It is shown that due to the hemodynamic imbalance the vegetative regulatory activity deviates towards sympathetic sections. The increase in tension index speaks of the increase in the central regulation activity, which in turn ensures mobilization of additional functional reserves in the organism. In patients with severe cerebrovascular diseases, complicated by an acute stroke, a significant violation of dual interaction between divisions of the autonomic nervous system leads to homeostatic shifts towards sympathetic influence on the cardiovascular system.
