The instantaneous heart rate changes were examined in 12 forest workers during following tests: increasing (up to refusal) dynamic load on ergometer, rest in erect position, static load (about 75% of body weight) in erect position. The ECG signal, carrying information on heart rate, was amplified and processed by means of an especially designed heart rate analyzer. The dynamics of heart rate changes was evaluated through the analysis of differences of subsequent instantaneous heart rates and of distributions of heart rate accelerations and decelerations during the tests. Significantly different distributions of instantaneous heart rate changes as well as of accelerations and decelerations were observed for different loads.
在以下测试过程中，对12名林业工人的瞬时心率变化进行了检查：在测力计上增加（直至无法承受）动态负荷、直立位休息、直立位承受静态负荷（约为体重的75%）。携带心率信息的心电图信号通过专门设计的心率分析仪进行放大和处理。通过分析测试期间后续瞬时心率的差异以及心率加速和减速的分布情况，来评估心率变化的动态过程。对于不同负荷，观察到瞬时心率变化以及加速和减速的分布存在显著差异。
