Abstract Functional indicators act in two forms – both criteria of a pathological state, and its weights. The solution of expected tasks is possible for many of them or their combinations. The diagnostics of a pathological state itself is based on limited quantity of indicators. An assessment of its weight and furthermore forecasting will demand the broadest possible attraction of their wider potential. With a small informative value in recognition of the most pathological state, they are irreplaceable in determination of its clinical importance as on influence on current health state of the patient, and on the next and remote forecast. On the basis of interaction these systems of a human body, it is supposed that digestive, blood circulations, cardiovascular systems and others, are closely connected with each other by functional ratios. Minor change of a state in one system can render considerable violations in others. In article it is offered to estimate influence of small variations in human organs (a liver, kidneys, intestines and others), caused by weak mechanical waves of ultrasonography on cardiovascular system. The results of pilot ultrasonic studies are given in various internals of patients in Naval clinical hospital (Vladivostok). It is shown that the insignificant increase in radiation energy of new devices, demands correction of standard inspection time values of various patients’ bodies. The electric instability of a myocardium and other adverse reactions of cardiovascular system is noted on the basis of the analysis the patients electrocardiogram after carrying out ultrasonography. These changes are an objective indicator of interaction of a human body functionality.
