Introduction. The Q-Eurocardio system is a noninvasive hardware-software device that works together with the computer and is based on the method of the quantitative seismocardiography. Main task of this apparatus is absolute noninvasive monitoring of the cardiovascular function.

Results. The equipment was tested on a group of children from Beslan. They were invited to the recondition stay in Karlovy Vary by the Czech Government as they suffered from trauma after the terrorist attack at school. Especially the stress index was examined. Normal values of the stress index (SI) are 150. At the beginning of the recondition stay the mean values of SI were 486,1. It was found that at the beginning of their stay the values were very high, at the end of their stay the values were lowered but not yet normalized.

 Conclusions.
It was proved that

1.  the Q-Eurocardio system offers specific information  about   functional  changes  of  thecardiovascular system regulation which preceded the structural changes coming later

2. the stress index is a very sensitive parameter for recognition of the autonomic nervous system dysfunction and disturbances
