Abstract
By using of the method of tetrapolar impedance rheopletysmography we studied the phasic structure of cardiac cycle in children of junior school age. We have shown that a decrease of cardiac cycle duration in children is due to a decrease of the common diastole duration, the mean fraction of which in children of six years is 48.58% from the cardiac cycle duration. With age the duration of cardiac cycle increases. In 12 y.o. children this parameter is significantly higher (0.702 +/- 0.020s) that that observed in 6 y.o. children (0.636 +/- 0.017s). The shortest duration of cardiac cycle is detected in 10 y.o. children (0.617 +/- 0.018 s).
Keywords:
