基于心率变异性与精神负荷关系的研究
Study of the Relationship Between Heart Rate Variability and Metal Stress
摘要
Abstract
Objective To explore the changing trend of sympathetic nervous system and parasympathetic nervous system with the changing of mental stress, this process was accomplished by studying the relationship between heart rate variability parameters and mental workload in healthy adult males. Methods First, a mental stress experiment system was designed based on N-BACK experimental paradigm. Second, the mental stress test was performed on 30 male college graduate to acquire ECG signal under different mental stress level. Then the heart rate variability of ECG was analyzed. Results The calculation results showed that RMSSD as well as SDNN in time domain and the high frequency power components in frequency domain were decreased with the increasing of mental stress. Conclusion This study has reference value for the assessment of autonomic nervous system state and mental stress.关键词
