    Hyperventilation syndrome is linked to vestibular hyperreactivity, particularly an increased gain in the vestibulo-ocular reflex (VOR). The velocity step test may help detect hyperventilation syndrome in patients with dizziness.

    Area of Science:

    • Neurology
    • Otolaryngology
    • Vestibular System

    Background:

    • Hyperventilation syndrome is a condition characterized by rapid, deep breathing.
    • Vestibular hyperreactivity can manifest as an exaggerated response to vestibular stimuli.
    • The vestibulo-ocular reflex (VOR) stabilizes gaze during head movements.

    Purpose of the Study:

    • To investigate the relationship between hyperventilation syndrome and vestibular hyperreactivity.
    • To determine if vestibular testing can aid in diagnosing hyperventilation syndrome.

    Main Methods:

    • Assessed vestibular hyperreactivity using velocity step responses in patients with hyperventilation syndrome.
    • Examined vestibular responses in normal subjects after induced hyperventilation.
    • Evaluated vestibular hyperreactivity in patients with dizziness and no other apparent abnormalities.

    Main Results:

    • 77% of patients with hyperventilation syndrome exhibited vestibular hyperreactivity, primarily due to increased VOR gain and time constant.
    • Forced hyperventilation in normal subjects induced similar vestibular effects.
    • 75% of dizzy patients with vestibular hyperreactivity had an underlying hyperventilation syndrome.

    Conclusions:

    • Vestibular hyperreactivity, specifically altered VOR gain and time constant, is associated with hyperventilation syndrome.
    • The velocity step test, even without hyperventilation provocation, appears to be a valuable tool for detecting hyperventilation syndrome in patients presenting with dizziness.
