摘要
为研究精神负荷对心率变异性(HRV)的影响,在选拔飞行员的心理生理储备测试中,对HRV进行了非线性动力学分析。结果表明,加载精神负荷后受试者的HRV的三个非线性参数都有不同程度的降低。进一步分析还发现分解后的HRV的三个非线性参数和受试者的心理生理储备有一定的相关性,有可能做为衡量心理储备的一项指标.
Many reasearch works have been done on effects of mental load on Heart Rate Variability(HRV),however,the use of nonlinear dynamics in signal processing of HRV has not been reported before.The effects of mental load on HRV of pilots were analyzed with nonlinear dynamic analyzing methods .Results showed that three nonlinear parameters de-creased in different extents after mental loading,Further analysis with decomposed HRV da-ta demonstrated that the psychological potential capability is consistent with those parameters.
