The invention relates to the field of medicine, specifically - to cardiology and practical health care.; The proposed device (step machine) is a monolith in the form of stairs, consisting of four steps, with the height from the floor steps of 0.1 m, 0.2 m, 0.3 m and 0.4 m and a width in the lateral steps section of 0.4 m.; Compared with the prior art, the device easier to use because It is a monolith, thereby not required to expend additional time and effort for the compilation of individual sections of the desired step height. Decreases as the time of the test. In addition, using the proposed device test exercise tolerance can be performed continuously, which enables standardization and more accurate evaluation of tolerance.
