Abstract

Hyperventilation Induced Nystagmus (HVIN) is associated with chronic peripheral vestibular disease. Objectives: 1) Study the correlation of HVIN with patient’s co-morbid diseases and otological diagnosis. 2) Study the association between HVIN and the result of the caloric test. Materials and Methods: Patients were evaluated in the dizziness clinic during the years 2010-2011. HVIN was assessed after hyperventilating for 60 sec, during the Videonystagmography (VNG) exam. Patients were summarized as having unilateral peripheral vestibular diseases, central diseases or unknown. Results: One hundred and fifty patients were examined. Comorbidities included cardiovascular disease (N=24), cardiovascular risk factors (N=66), respiratory diseases (N=12), neurological diseases (N=23) and psychiatric disorders (N=9). HVIN was observed in 32/150 (21.3%) patients and ranged from 8.3% (respiratory disease) to 33.3% (in the psychiatric patient group). Among patients with unilateral canal paresis, 9/40 (22.5%) exhibited HVIN, compared to 23/110 (20.9%) patients with a negative caloric test (p-value 0.833). Six out of 39 patients (15.3%) with central diseases exhibited HVIN, compared to 16/66 (24.2%) among patients with peripheral diseases (p-value 0.555). Among patients with a normal caloric exam and positive HVIN 12/23 (52%) had peripheral disease. Conclusion: We did not find an association between HVIN and patients characteristics or comorbid disease. Our study also did not find association between HVIN and the final diagnosis.
