title: [The relevance of high stimulus rate ABR and recurrent vertigo and its clinical significance].
abstract: OBJECTIVE
  To study the relevance of the high stimulus rate auditory brainstem response(auditory brainstem response, ABR) test in recurrent vertigo, investigate the cause of recurrent vertigo, and provide important help for the clinical treatment.
  
  
  METHODS
  One hundred and one cases with recurrent vertigo were retrospectively analyzed, and high stimulus rate ABR were tested and compared in attack episodes and intermittent episodes.
  
  
  RESULTS
  The abnormal difference between ABR I and V latency was selected as parameters. The abnormal rate of high stimulation ABR was 56.4% in patients with recurrent episodes of vertigo many times (2 and above), of which the highest rate was 71.9% in MV patients, and the second one was BPPV. The abnormal rate of high stimulation ABR was 14.9% in patients during medication or intermittent episodes. The abnormal rate in all groups decreased obviously as compared to attack episodes.
  
  
  CONCLUSIONS
  Abnormal rate of high stimulus rate ABR correlates well with recurrent vertigo significantly. The inner ear microcirculation may result in the attack of recurrent vertigo.
