ABSTRACT

Introduction. In clinical literature, autonomic manifestations of vestibular dysfunction and dizziness are well established. However, few studies that demonstrate the effect of vestibular stimulation on the autonomic nervous system through the measurement of heart rate variability (HRV). Material and methods. A convenience sample of 15 healthy subjects between 25 and 55 years (studying 30 ears), randomly chosen from a population of Mexico City was noted. Vestibule was stimulated by instilling water in the ear canal at constant temperature, quantity and pressure, via an automatic irrigator. Quantifying heart rate and the difference between RR intervals of the ECG. Results. In spectral analysis, no significant differences were observed in the components of high and low frequency, or the ratio of components of high and low frequency. Conclusions. It was not possible to establish a significant difference between basal heart rate or without vestibular stimulation, compared with heart rate during standarized vestibular thermal testing.
