[Reaction of the autonomic nervous system to carbon dioxide baths in patients with cardiovascular diseases].

Holter ECG monitoring was for the first time accomplished before, during, and several hours after a balneologic procedure (carbon dioxide bath) with simultaneous analysis of cardiac rhythm variability. Results of the study suggest the possibility of high-quality ECG monitoring n the course of balneologic treatment. Its data can be used to evaluate cardiac rhythm variability and estimate the degree of activation of sympathetic and parasympathetic components of the vegetative nervous system in patients with cardiovascular diseases in response to balneotherapeutic procedures.
