[A microcomputer system of biotechnical feedback].

A microcomputer system has been constructed and developed for biofeedback research and clinical biofeedback training. Hardware and software enable on-line data acquisition, storage and real-time analysis with visual feedback of chosen parameters, while changes in other physiological variables are recorded and monitored. The software handles control of experimental sessions, data reduction, statistics, data base management and output document forming. Computer analysis of pulse transit time biofeedback training with multiple cardiovascular monitoring in experimental and clinical setting outlined contributions of sympathetic and parasympathetic influences on observed patterns of cardiovascular modifications.
