我们通过分析内源性儿茶酚胺水平和收缩时间间隔，研究了人类应激时交感神经元功能与左心室功能之间的关系。结果表明，应激性认知任务的表现伴随着血浆儿茶酚胺、心率（HR）、血压（BP）和收缩时间间隔的变化。心血管反应与血浆肾上腺素(E)和去甲肾上腺素（NE）水平显著相关。血浆儿茶酚胺与收缩时间间隔之间的关系被认为反映了交感神经-肾上腺髓质在压力下对左心室功能的影响。
We studied the relationship between sympathetic neuronal function and left ventricular performance during stress in humans by analysis of endogenous catecholamine levels and systolic time intervals. The results showed that performance on a stressful cognitive task was accompanied by changes in plasma catecholamines, heart rate (HR), blood pressure (BP), and systolic time intervals. The cardiovascular responses were significantly correlated with plasma levels of epinephrine (E) and norepinephrine (NE). The relationship between plasma catecholamines and systolic time intervals is thought to reflect sympatho‐adrenomedullary impact on left ventricular performance during stress.
