Diagnosis
Hyperventilation syndrome is a remarkably common cause of dizziness complaints. About 25% of patients who complain about dizziness are diagnosed with HVS.
A diagnostic Nijmegen Questionnaire provides an accurate diagnosis of Hyperventilation without triggering symptoms. It has been used extensively in many scientific studies.
