Esforço auditivo e registro do controle parassimpático do coração durante o reconhecimento de sentenças: estudo piloto

Abstract: Introdução: Medidas psicofisiológicas do sistema nervoso autônomo em resposta a tarefas auditivas podem fornecer um meio de quantificar os efeitos do esforço auditivo. Objetivo: Comparar a modulação parassimpática da frequência cardíaca em situações de escuta distintas e determinar se a variabilidade da frequência cardíaca (VFC) é um índice psicofisiológico sensível para mensurar o esforço auditivo. Método: Estudo piloto, observacional, transversal e prospectivo. Participaram 14 adultos normo-ouvintes, de ambo… Show more

“…From another perspective, currently, studies in the area have focused mainly on analyzing the association between Heart Rate Variability (HRV) and auditory evoked potentials, in adults with normal hearing, reporting the interaction between the autonomic control of heart rate with the cochlear nerve (4) , between the heart rhythm with the thalamo-cortical, cortical-cortical and auditory cortex (5) , and between cardiac autonomic modulation with the Cortical Auditory Evoked Potential (6) . Other research analyzing HRV, in individuals without and with hearing loss, through tasks for measuring listening effort (7)(8)(9) Therefore, when considering the scientific evidence documented by literature that demonstrated the relationship between heart rhythm control and hearing, we hypothesized about the possibility that there is an association between HRV-the oscillations in the time intervals between consecutive heartbeats-and auditory sensitivity.…”
