P300 and contingent negative variation (CNV) were recorded in depressive inpatients with and without history of suicide attempt. The results show a significant reduction of both P300 and CNV in patients who had attempted suicide as compared with patients who had not. Moreover, a significant correlation was found between the suicidal risk scale and CNV amplitude. Psychophysiological and biochemical implications are discussed.
对有和没有自杀未遂史的抑郁症住院患者记录了P300和关联性负变（CNV）。结果显示，与未自杀未遂的患者相比，有自杀未遂的患者的P300和CNV均显著降低。此外，发现自杀风险量表与CNV波幅之间存在显著相关性。对心理生理学和生物化学意义进行了讨论。
