A continuous telemetric registration of the cardiac contraction rate was made in 534 persons performing various physical exertions. The ensuing epxerimental graphs of changes in the rhythm obtained under the effect of physical loads are described by mathematical formulas. Three types of changes in the rhythm in effort have been established, viz. linear, exponential and logarithmic. To determine cardiac function quantitative coefficients, reflecting the rate of the cardiac rhythm coming up to the working level and relationship between the areas of the steady state cardiac contractions frequency phase and that of its rapid increment, are proposed.
对534名进行各种体力活动的人进行了心脏收缩率的连续遥测记录。根据数学公式描述了在体力负荷作用下获得的随后的心律变化实验图。已确定了用力时心律变化的三种类型，即线性、指数和对数型。为了确定心脏功能的定量系数，提出了反映心律达到工作水平的速率以及心脏稳定收缩频率阶段与其快速增加阶段之间关系的系数。
