Monitoring system of heart rate indeces

Diagnostic indeces were suggested for estimation of human state. These indeces hare based on heart rate variability analysis and its reflect of vegetative nerves system activity. Monitoring system for proposed indeciones computation in real time was developed. It consists of measuring block which is connected to personal computer in RS232C standard and optical sensor for distal pulse registration. The developed system may be used in psychophysiology and scientific investigation for human state estimate.
