[Biofeedback of human heart rate: adaptive module]

Ecological issues, that are not in line with the adaptive opportunities of man, prompt the designing of computer-based systems for psychophysiological support of traditional methods of prevention, diagnostics and rehabilitation. An adaptive module of biofeedback was developed for monitoring the human heart rate. The system can be applied in a variety of medical spheres, like evaluation of adaptive potentialities of different body systems, enhancing of the body's reserve and of its efficiency; mobilization of latent or lost abilities to adapt; training of skills of relaxation, self-regulation and self-control; correction of the condition of persons at different stages of occupational, ecological psychological and social stress; and preliminary psychophysiological preparation for responsible operator tasks.
