Abstract: Objective To study the discharges regularity of ambulatory electroencephalogram (ambulatory,EEG,AEEG)during sleep and hyperventilation(HV)-induced EEG. Methods Features of epileptiform discharges of AEEG and HV-induced EEG were evaluated comparatively in 65 cases with frontal lobe epilepsy. Results The epileptiform discharge rate of HV-induced EEG was evidently lower than that of AEEG during the shallow sleep period (non-rapid-eye-movement phase 1 and 2,NREM phase 1 and 2),which had statistical significance(P＜0.01);however,the rate of HV-induced EEG had no significant difference from that of AEEG during the awake period and deep sleep period(NREM phase 3 and 4)(P＞0.05). Conclusions The epileptiform discharge rate of AEEG during the shallow sleep period is obviously higher than that of HV-induced EEG in patients with frontal lobe epilepsy,and thus sleep EEG is helpful to enhance the diagnostic rate of epileptiform discharges in these patients.
