SUMMARY:

Introduction. Among the changes present in HIV, there is an imbalance of cardiac autonomic control, which can lead PLWHA to prematurely present cardiovascular diseases. Thus, therapies that assist pharmacological treatment and enhance the results of non-drug therapies are essential for improving health. Therefore, the objective of the study is to evaluate the acute effect of atrial transcutaneous electrostimulation of the vagus nerve on the cardiac autonomic control of people living with HIV / AIDS. Methodology. The research is characterized as a controlled, randomized, crossover and double blind clinical trial, with a sample composed of 21 people with HIV / AIDS who have been using ART for more than 6 months and who were in a physical detraining period for 3 months. university extension project that uses “Viver Mais” physical exercise. The individuals were randomly allocated to two groups: taVNS (active stimulation) and Sham-t (inactive stimulation), where they were then crossed. For atrial transcutaneous electrostimulation of the vagus nerve, a TENS device (Tensmed Iv 4034es Carci, Brazil) was used, with modified electrodes. To evaluate the cardiac autonomic control, the heart rate variability process was performed, where 5 minutes were analyzed and the measures of the average HR, RMSSD, LF, HF, LF / HF, SD1, SD2 and SD1 / SD2 were selected. The two-way ANOVA of repeated measurements was used to verify the effect of electrostimulation on the auricular nerve on cardiovascular parameters (Time [4] x condition [2]). For all analyzes, a significance level of 5% was adopted. Results. The taVNS group increased LF from 25'-30 '(∆ = 0.281, 95% CI = 0.068 - 0.494, p = 0.006) and after the experimental session (∆ = 0.291, 95% CI = 0.051 - 0.531, p = 0.012). The Sham-t group increased LF since the beginning of the 5'-10 'protocol (∆ = 0.334, 95% CI = 0.120 - 0.548, p = 0.001), 25'-30' (∆ = 0.356, 95% CI = 0.190 - 0.523, p <0.001) and after the session (∆ = 0.421, 95% CI = 0.156 - 0.686, p = 0.001). Conclusion. TAVNS in PLWHA may be a good strategy for improving cardiac autonomic control, however, new protocols need to be tested and over a period to demonstrate the possible benefits of an intervention with taVNS.
