Transcutaneous electrical stimulation of the auricular vagus nerve (TENS) is a promising method of neuromodulation of the autonomic nervous system in patients with various pathologies. The use of this method requires the determination of a reliable biomarker of successful activation of the vagus nerve using TENS. Currently, most studies focus on the assessment of heart rate variability (HRV) as a marker of the functioning of the autonomic nervous system. Despite the physiological justification of HRV as a biomarker for TENS, the data on the effects of TENS on HRV are ambiguous. In some studies, a significant decrease in the ratio of spectral characteristics (LF/HF) in active TENS was found in comparison with fictitious stimulation (sham), which indicated an increase in the parasympathetic component of HRV. However, other studies have not revealed an increase in HRV.

Secondary | HR dynamics | Changes in the HR level relative to the initial and after the end of stimulation in the groups of active and fictitious stimulation | This parameter will be evaluated before stimulation initially at rest, in the first 5 minutes of stimulation, in the second 5 minutes of stimulation and after the end of stimulation. | |
Secondary | Dynamics of SDNN | Changes in the level of SDNN relative to the initial and after the end of stimulation in the groups of active and fictitious stimulation | This parameter will be evaluated before stimulation initially at rest, in the first 5 minutes of stimulation, in the second 5 minutes of stimulation and after the end of stimulation. | |
Secondary | Dynamics of IVB | Changes in the level of IVB relative to the initial and after the end of stimulation in the groups of active and fictitious stimulation | This parameter will be evaluated before stimulation initially at rest, in the first 5 minutes of stimulation, in the second 5 minutes of stimulation and after the end of stimulation. | |
