The effect of amiodarone on the spectral parameters of heart rate variability in patients with various forms of atrial fibrillation

In this study, spectral parameters in patients with various forms of atrial fibrillation and the effect of the class III antiarrhythmic drug amiodarone on these parameters were studied. The use of spectral analysis of heart rate variability (hereinafter referred to as HRV) when choosing a drug for the treatment of arrhythmia and arterial hypertension is becoming increasingly widespread in experimental and clinical practice. This method, thanks to the mathematical analysis of the time and frequency characteristics of heart rate variability, allows you to get an idea of slow oscillatory processes that constantly exist in the body and have the properties of autowaves. The use of this method gives an idea of the role of various departments of the autonomic nervous system (sympathetic and parasympathetic), as well as the implementation of humoral mechanisms in the implementation of the chronotropic function of the heart.
