Previous studies have already demonstrated that
auditory stimulation with
music influences the
cardiovascular system. In this study, we described the relationship between musical
auditory stimulation and
heart rate variability. Searches were performed with the
Medline, SciELO,
Lilacs and Cochrane databases using the following
keywords "
auditory stimulation", "
autonomic nervous system", "
music" and "
heart rate variability". The selected studies indicated that there is a strong correlation between
noise intensity and vagal-sympathetic balance. Additionally, it was reported that
music therapy improved
heart rate variability in
anthracycline-treated
breast cancer patients. It was hypothesized that
dopamine release in the striatal system induced by pleasurable
songs is involved in cardiac autonomic
regulation. Musical
auditory stimulation influences
heart rate variability through a neural mechanism that is not well understood. Further studies are necessary to develop new
therapies to treat cardiovascular disorders.
