[Autonomic control and functional condition of suprasegmental structures of the brain in patients with heart rhythm disorders and vasculo-autonomic dystonia]. / Otsenka vegetativnoi reguliatsii i funktsional'nogo sostoianiia nadsegmentarnykh struktur mozga u bol'nykh s narusheniiami ritma serdtsa i vegetativno-sosudistoi distoniei.

A study was made by the method of combination of electroencephalography (EEG) and variational pulsimetry in 157 patients to determine the background vegetative tone and that very tone during conducting functional tests aimed at activating of sympathetic and parasympathetic portions of the nervous system. Criteria have been established characterizing the vegetative tone. Particular features are described of changes in the power of the EEG wave spectra while conducting tests in those groups being different in their baseline vegetative tone. The percentage is estimated of the incidence rate of the cardiac rhythm disturbances in those groups being different in their vegetative tone.

Sixty-eight patients with different disorders of the cardiac rhythm were examined in ambulatory conditions. The complex of noninvasive examinations included: echocardiography, Holter monitoring, bicycle ergometry [correction of veloergometry] and transesophageal cardiostimulation with performance of diagnostic and pharmacological tests. The obtained data permitted to evaluate disorders of automatism and conduction at different levels of the cardiac conduction system, to identify paroxysmal tachyarrhythmia and realize selection of antiarrhythmic agents.
