[Radioelectrocardiographic record in workers employed in railroad repair shops].
Cardiac response to the physical effort due to occupational work was studied in 33 workers employed in a railway repair shop by means of radioelectrocardiography. The HR ranges, HR mean values and r-ecg changes in different professional groups are described. Attention was paid to the pronounced sinus arrythmia observed in subjects performing hard work. The quantitative and qualitative changes of the obtained results were described and the difficulties in the evaluation of r-e.c.g. records obtained during dynamic examination were emphasized.
