title: [An assessment of the information value of the indices from analyzing cardiac variability (ACV)in situations related to neuro-emotional stress].
abstract: A group of 67 students in medicine, sitting for an examination on obstetric and gynaecology, were subject to examinations in the periods: before and immediately after the examination. Taking into consideration the analysis of the heart variability (AHV), the pre-examination period shows more strongly expressed stress component, the main constituent of which is the sense of fear. Between the performance and the changes in the indices of the analysis of the heart variability, reflecting the total functional state, fatigue and distress, no specific differences were discovered. The sexual differences were expressed only in the way that the stress discomfort in women dies out more slowly than in men. A conclusion is made, that the pulse frequency and the indices of the analysis of the heart variability, related to the variability, including the combined index - CI, reflect more clearly the induced by the examination model emotional discomfort, than the indices, obtained from the frequency spectrum of the heart rhythm (Czechoslovakia).
