Conclusion
taVNS is a safe, easy-to-perform intervention and can benefit HF by improving heart rate variability parameters (SDNN), which indicates better autonomic balance. In intragroup comparisons before and after treatment, improved quality of life and the 6-minute walk test in the taVNS group were also shown.Based on these results, one can suggest expanding the indication of auricular vagal neuromodulation in patients with HF, although new studies with a larger number of patients are needed to answer the questions raised by the present study.Study associationThis article is part of the thesis of master submitted by Sergio Livio Menezes Couceiro, from Programa de Pós-graduação em Cardiologia pela Universidade Federal Fluminense.Sources of funding: There were no external funding sources for this study.
