压力是当今社会的一个大问题。因此，能够测量压力可能有助于解决这个问题。虽然压力有心理根源，但它影响人体的几个生理过程：颈部肌肉张力增加，几种激素浓度变化，心率（HR）和心率变异性（HRV）的变化。大脑通过自主神经系统（自主神经系统分为交感神经和副交感神经分支）的刺激来支配心脏。交感神经活动导致HR增加（例如在运动时），而副交感神经活动导致HR降低（例如在睡眠时）。这两个回路不断相互作用，这种相互作用反映在HRV上。因此，HRV提供了一种表达ANS活性的方法，并可能因此提供一种应激方法。因此，我们探索了在施加压力的情况下衡量人力资源和HRV的方法。我们记录了一组28名受试者在休息和有精神压力时的HR和HRV变化。结果表明，HR和HRV随心理任务的变化而变化。因此，HR和HRV记录可能具有测量压力水平和指导预防措施以减少压力相关疾病的潜力。
Stress is a huge problem in today’s society. Being able to measure stress, therefore, may help to address this problem. Although stress has a psychological origin, it affects several physiological processes in the human body: increased muscle tension in the neck, change in concentration of several hormones and a change in heart rate (HR) and heart rate variability (HRV). The brain innervates the heart by means of stimuli via the Autonomic Nervous System (ANS), which is divided into sympathetic and parasympathetic branches. The sympathetic activity leads to an increase in HR (e.g. during sports exercise), while parasympathetic activity induces a lower HR (e.g. during sleep). The two circuits are constantly interacting and this interaction is reflected in HRV. HRV, therefore, provides a measure to express the activity of the ANS, and may consequently provide a measure for stress. We therefore explored measures of HR and HRV with an imposed stressful situation. We recorded changes in HR and HRV in a group of 28 subjects at rest, and with a mental stressor. The results suggest that HR and HRV change with a mental task. HR and HRV recordings may have the potential, therefore, to measure stress levels and guide preventive measures to reduce stress related illnesses.
