Diagnostic yield of five minutes compared to three minutes hyperventilation during electroencephalography

Highlights • Hyperventilation (HV) for 5 min has a higher diagnostic yield than 3 min HV. • 16% of seizures triggered by HV occurred during the last 2 min of HV. • For the interictal EEG abnormalities this was 30%. • Only few patients (1%) could not complete the last 2 min of HV. • No major adverse...
