RESUMO
OBJECTIVE: The purpose of the study was to present the results of 15-year application in practical cardiology of the method of high-resolution registration and analysis of heart rate variability (HRV) for diagnosis of the cardiovascular pathology. METHODS: Database consists of more than 46 thousand cases with different cardiovascular diseases. Here are shown some peculiarities of the HRV analysis and perspective possibilities of the method, named rhythmocardiography. RESULTS: Experience of rhythmocardiography use in cardiology supposes a wide perspective of this method application for the cardiovascular diagnosis. It allows to define various disregulations of the sinus node pacemaker activity, characterized for every form of the coronary artery disease, cardiac arrhythmias, stages of the hypertension disease, syndrome of autonomic cardioneuropathy, high risk of lethal outcome and etc. The rhythmocardiography may be used in treatment choice, in control of the therapy and studying of the autonomic efficacy of some drugs. CONCLUSION: Thereby, rhythmocardiography is an informative method for diagnosis of the cardiovascular pathology. The high-resolution measurement of HRV and following such computer analysis in time-domain and frequency-domain can be considered highly informative, because of reliable correspondence and comparable RCG-results with data of other studies and clinical symptoms of the diseases.
