This article describes the method of registration electrocardiogram and physical activity which patient feels during the examination process. The represented scheme of research with registration of a load, which includes portable pulsometer, cardioregistrator fixing electrocardiogramm, frequency of cardiac contractions, ST segment shift, the trainer is a stepper to wichpeddal a block of load registation is connected. The person on stepper, tests a load peer to potential energy, spent during research. On the basis of the specified method the hardware-software complex of registration of a load is developed for functional diagnostics, there is a block diagram presented.
