The article demonstrates an algorithm to evaluate functional state of operators exposed to ecologic hazards. The evaluation of the functional state includes analysis of the heart rhythm registered for 2 minutes. The functional state is assessed through an Indicator of Regulatory Systems Activity (IRSA), obtained by summation of all the values in modulus. IRSA values define 5 functional states: norm; functional strain moderate, marked and extreme; asthenia of regulatory systems. The algorithm suggested differs from the known ones in some features as follows. The diagnosis of heterotopic arrhythmia serves for more precise code demonstrating the heart automatism; formed on the basis of variation coefficient, the code demonstrating stability of the regulation proves the status of stable or disordered regulation; the code demonstrating activities of subcortical neural centers is formed on the basis of measured relative capacity of primary and secondary respiratory waves.
本文展示了一种评估暴露于生态危害中的操作人员功能状态的算法。功能状态评估包括对记录2分钟的心律进行分析。功能状态通过调节系统活动指标（IRSA）进行评估，该指标通过对所有绝对值求和获得。IRSA值定义了5种功能状态：正常；功能应激轻度、中度、重度和极重度；调节系统衰弱。所提出的算法在一些特征上与已知算法不同，具体如下。异位心律的诊断用于更精确地编码以展示心脏自律性；基于变异系数形成的展示调节稳定性的编码证明了调节处于稳定或紊乱状态；展示皮质下神经中枢活动的编码是基于测量的一次和二次呼吸波的相对容量形成的。
