.健康受试者、冠心病患者、动脉高血压患者和血管调节无力综合征患者进行了标准化工作试验。根据评级方法的心脏频率和评级的自觉劳累在不同的工作负荷进行了评估。不同的措施的物理工作能力进行了估计。血管调节性乏力患者和动脉高血压患者，尽管不太明显，但与健康对照组相比，他们对运动与心率的关系的评价更低，特别是在低评价水平。相反，冠心病患者对运动的评价更高，特别是在高评分时，与心率有关。在研究的所有患者组中，心率的平均增加相对于运动评分的给定增加较小，即对于心率的给定增加，运动评分的增加大于健康对照组。次最大体力劳动能力的测量是基于心率和主观用力等级。与同龄对照组相比，VA组基于心率的体力工作能力测量值与基于自感劳累评级的体力工作能力测量值之间的比值较低，而冠状动脉功能不全患者的比值较高。在测试期间具有低"最大"性能的患者也具有低次最大体力工作能力，其根据心率以及感知用力等级来估计。不同患者组之间，尤其是冠心病患者与血管调节无力综合征患者之间的差异具有鉴别诊断价值。
. A standardized work test has been performed by healthy subjects, patients with coronary heart disease, patients with arterial hypertension, and with the vasoregulatory asthenia syndrome. Heart frequency and rating of perceived exertion according to a rating method were assessed at various work loads. Different measures of physical working capacity were estimated. Patients with vasoregulatory asthenia—and patients with arterial hypertension, although less markedly—rated the exertion to be less in relation to heart frequency than healthy controls, particularly at low rating levels. On the contrary, patients with coronary heart disease rated the exertion to be higher, particularly at high ratings, in relation to heart frequency. In all patient groups studied, there was a smaller mean increase in heart rate in relation to a given increase in rating of exertion, i.e. for a given increase in heart rate there was a greater increase in rating of exertion than in healthy controls. Submaximal measures of physical working capacity were based on heart rate and rating of perceived exertion. The ratio between measurements of physical working capacity based on heart rate and those based on rating of perceived exertion was low in the VA group and high in patients with coronary insufficiency when compared with controls of equal age. Patients with a low “maximal” performance during the test also had a low submaximal physical working capacity estimated from heart frequency as well as from rating of perceived exertion. The difference found between the various patient groups, especially that between patients with coronary heart disease and patients with the vasoregulatory asthenia syndrome is of differential diagnostic value.
