[Heart rhythm variability in individuals with different respiration frequency].
Variability in heart rhythm and respiration frequency in the men aged 17-23 were measured at rest and during mental loading. It was found that the variability level ofcardio intervals was higher in individuals with low and high respiration frequency when compared with individuals with average respiration frequency at rest. During mental loading, the biggest changes in the amplitude of the heart rhythm were marked in individuals with high respiration frequency.
