Abstract
It is well known that the decrease of the Heart Rate Variability (HRV) is related to a number of important pathologies involving cardiovascular system as well as psychological and psychiatric disorders. In such case a prompt recover of HRV and, in particular, of parasympathetic modulation is required in the ANS (Autonomic Nervous System). In order to pursue this objective in the present paper. The physical technique of the brain entrainment has been used. We have recorded R-R time intervals estimated from the QRS complex in the ECG. One time the R-R signal has been recorded during rest condition of the subject and the second time during alpha brain stimulation. The following step has been to analyze the data performing the Fast Fourier Analysis that is able to quantify the ANS activity of modulation on heart rhythm. We have found that, respect to the rest case, alpha brain stimulation induces a constant improvement in the total power spectral density (and thus induces an increase in total heart rhythm variability) and in particular in the parasympathetic (HF) band spectrum. The result is of interest for further consideration by clinicians and researchers of brainwave entrainment (BWE) as basic therapeutic tool in a so serious field of neurology and related pathologies.
