Spectral analysis of heart rate variability in patients with newly diagnosed atrial fibrillation

Abstract

Spectral analysis of heart rate variability gives an idea of the role of the autonomic nervous system in the regulation of chronotropic heart function and can be used to evaluate the effectiveness of drug therapy. The selection of drug therapy taking into account the individual clinical form of atrial fibrillation, as well as the vegetative status of the patient, will undoubtedly increase the effectiveness of treatment. In this study, spectral parameters were studied in patients with newly diagnosed atrial fibrillation and the effect of the antiarrhythmic drug class III miodarone on these parameters.
