摘　　要：目的探讨立位耐力不良飞行员模拟空中环境下心脏自主神经功能调节状态和心理生理反应特点，为空中晕厥的诊断提供客观的评价方法。方法对２２名立位耐力不良（不良组）飞行员进行了连续动态心电记录和模拟飞行条件下的心理生理参数测定与心率变异性（ＨＲＶ）分析，并与１５名立位耐力正常的健康飞行员（健康组）做了对比。结果不良组飞行员在模拟仪表飞行中心理生理储备能力明显降低，表现为完成两项任务的质量和处理信息速度的能力较健康组低（Ｐ＜０．０１）；心血管自主神经功能严重失调；心理生理储备值与ＨＲＶ多数指标之间存在明显的相关性。结论结合模拟仪表飞行条件下的心理生理负荷评定和ＨＲＶ分析能较客观地反映立位耐力不良飞行员心血管自主神经功能障碍的发生机制和调节规律，为空中晕厥的诊断提供量化的指标。Objective To explore autonomic nerve function and psychophysiological response of pilots with orthostatic intolerance during flight in a simulator. Methods Psychophysiological parameters and heart rate variability (HRV) of 22 pilots with orthostatic intolerance (experimental group) and those of 15 healthy pilots with normal orthostatic tolerance (control group) were measured during flight in a simulator and the continuous dynamic electrocardiogram was recorded. Results Performance of dual task and processing information speed in experimental group were significantly lower than those in healthy group (P<0.01). There was cardiovascular autonomic nerve dysfunction in experimental group. Psychophysiological reserve was significantly correlated with many indexes of HRV. Conclusion Psychophysiological response and HRV analysis in two groups during flight in a simulator can reflect objectively cardiovascular autonomic nerve dysfunction in polots with orthostatic intolerance.
