Recently several studies have suggested that there are differences in autonomic balance between Type As and Type Bs. This study evaluates a sympathovagal interaction in Type A (n = 8) and Type B (n = 11) male students during a mental arithmetic task by power spectral analysis of heart rate variability. The low-frequency component to high-frequency component ratio was significantly greater in Type As than in Type Bs during a resting period. No significant differences were found in heart rate changes and blood pressure between the two kinds of subject groups. The present findings indicate that there was a significant difference in sympathovagal balance between Type As and Bs. Type As showed dominant sympathetic activity.
最近有几项研究表明，A型和B型人格者之间自主神经平衡存在差异。本研究通过心率变异性的功率谱分析，评估了8名A型和11名B型男学生在进行心算任务时的交感神经与迷走神经相互作用。在静息期，A型人格者的低频成分与高频成分的比值显著高于B型人格者。两组受试者在心率变化和血压方面未发现显著差异。目前的研究结果表明，A型和B型人格者之间的交感神经与迷走神经平衡存在显著差异。A型人格者表现出占主导地位的交感神经活动。
