Numerous studies have investigated the connection between autonomic control of heart rate (HR) and auditory stimulus. Yet, the literature lacks evidence of a close association between auditory brainstem processing and HR autonomic control. We aimed to evaluate and verify the relationship between auditory brainstem response (ABR) and HR variability (HRV) in healthy women. Forty‑six healthy female subjects, between the ages of 18 and 30 years old participated in the study. They were subjected to an audiometry examination, followed by rest for 10 minutes for HR recording. Next, ABR evaluation was completed discretely in both ears, with I, III and V wave components. Linear regression revealed that the root‑mean square of differences between adjacent normal RR intervals (RMSSD) and the triangular interpolation of RR interval (TINN) exhibited a significant association with Wave I in the right ear. These variables contributed to 28.2% (R²) of Wave I. In conclusion, there was a significant interaction between the autonomic control of HR and auditory processing in the right ear, suggesting that vagal tone interacts with the cochlear nerve.
许多研究调查了心率（HR）的自主控制与听觉刺激之间的联系。然而，文献中缺乏听觉脑干处理与HR自主控制之间密切关联的证据。我们旨在评估和验证健康女性中听觉脑干反应（ABR）与心率变异性（HRV）之间的关系。46名年龄在18至30岁之间的健康女性受试者参与了该研究。她们接受了听力测定检查，随后休息10分钟以记录心率。接下来，分别对双耳进行ABR评估，记录I、III和V波成分。线性回归显示，相邻正常RR间期差值的均方根（RMSSD）和RR间期的三角插值（TINN）与右耳的I波呈现显著关联。这些变量对I波的贡献率为28.2%（R²）。总之，HR的自主控制与右耳的听觉处理之间存在显著相互作用，表明迷走神经张力与耳蜗神经相互作用。
