ISOINTEGRAL MAP EXTREMA VARIABILITY DURING QRS COMPLEX AND ITS THIRDS IN YOUNG PEOPLE

摘要

We wanted to find out, whether there are differences on isointegral maps (IIMs) caused by sex and age. We constructed IIMs of 169 young healthy people (90 girls, 79 boys) divided into 6 groups according to the age and sex. For integration we used the QRS complex (whole and individual thirds). We compared extreme values of IIMs (maximum, minimum, peak-to-peak) and their location. Concerning extrema values, differences were found mainly between older boys and girls, what is in accordance with our expectations. Results of comparison of groups with different age are not unambiguous. Significant age differences in extrema location were found mostly between the youngest and the oldest group.
