摘　　要：目的:在诱发负性情绪条件下,研究健康男性中A型行为模式对心脏自主神经活动的影响。方法:采用两因素重复测量设计,分别考察A型和B型、高TH组和低TH组、高CH组与低CH组,在三种情绪应激状态下心率变异性各频域指标的差异。结果:无论按AB型整体分类,还是按CH和TH特质分类,在心率变异性(HRV)各频域指标上组间均无显著差异,被试类型与负性情绪应激水平均无显著交互作用。而三种情绪应激状态主效应显著,均表现为:在预期阶段和应对阶段两种应激状态下,交感神经功能的相对兴奋及迷走神经功能的相对抑制,交感-迷走神经的不平衡性增加。结论:健康男性中A型行为及其部分特质对心脏自主神经活动的影响均不显著,情绪应激对心脏自主神经活动的影响是直接而显著的,并且表现为冠心病病理状态下相似的变化特征。Objective： To study the effect of type A behavior pattern（TABP） on the heart autonomic nerve functional activity in healthy males in condition of negative emotion arousal.Methods： We adopted repeated measures of two factors,respectively investigating type A and type B,high TH group and low TH group,and also high CH group and low CH group,to see the differences of frequency domain HRV indices in three different emotional stress states between each two groups.Results： In comparison of A-B behavior patterns or both CH and TH traits,no significant deviations were found in frequency domain HRV indices between groups.The types of subjects and the levels of negative emotional stress had no significant interaction.On the other hand,the main effects of three different emotional stress states were significant,showing that,in both expecting phase and coping phase,the sympathetic nerve was excited while the vagus nerve was depressive relatively,causing the autonomic imbalance.Conclusion： In healthy males,the effects of type A behavior pattern and its partial traits upon the heart autonomic functional activity are not significant,while the effect of emotional stress is direct and significant with the changing feature that is similar to the pathological state of coronary heart disease（CHD）.
