摘　　要：Objective:To explore the features of event-related potentials P300 in heroin addicts.Methods:The auditory induced potentials of Pz were recorded in 22 heroin addicts and 22 control subjects.Results:(1)The latency of P3 in heroin addicts was delayed significantly than in control subjects( t =2.54, P <0.05);(2)The proportion of abnormal delay was significantly higher in experimental group(χ 2=8.32, P <0.01).Conclusion:There was cognitive impairment in heroin addicts.Objective:To explore the features of event-related potentials P300 in heroin addicts.Methods:The auditory induced potentials of Pz were recorded in 22 heroin addicts and 22 control subjects.Results:(1)The latency of P3 in heroin addicts was delayed significantly than in control subjects( t =2.54, P <0.05);(2)The proportion of abnormal delay was significantly higher in experimental group(χ 2=8.32, P <0.01).Conclusion:There was cognitive impairment in heroin addicts.
