【摘要】 目的:探讨慢性肺心病患者的负性情绪及其P300电位的临床价值。方法:对45例慢性肺心病患者和43例正常健康者分别进行了SAS、SDS及P300电位测定,并将结果加以比较。结果:慢性肺心病组SAS及SDS标准分显著高于对照组(P<0.01),P300电位成分中N2及P3潜伏期较对照组明显延长,P3波幅降低,存在显著性差异(P<0.01)。结论:慢性肺心病患者的负性情绪较为突出,P300电位对慢性肺心病患者临床诊治及预后判断有较高的价值。更多还原

【Abstract】 Objective:To explore the the negative emotion and value of P300 potentials with chronic obstructive pulmonary disease patients.Methods:SAS,SDS and P300 potentials test were used for forty-five chronic obstructive pulmonary disease patients and forty-three normal healthy people,and the results were compared in the two groups.Results: The scores of SAS and SDS scale with chronic obstructive pulmonary disease were significant higher than those in the controls(P<0.01).Latent period of N2 and P3 of P300 potentials in case group were longer than those in the controls and the amplitude of P3 of P300 potentials in case group was lower than that in the controls.There were significantiy difference between the two groups(P<0.01).Conclusions: Chronic obstructive pulmonary disease patients have remarkable negaitve emotion,P300 potentials have remarkable clinical value in evaluating the effect of treatment for chronic obstructive pulmonary disease patients.更多还原
