Interrelationship between age and heart rate, spectral parameters of heart rate variability, peak frequency of mid-frequency heart rate fluctuations, respiratory rate and coherence coefficient was investigated in normotensive healthy volunteers. Thereafter these parameters were correlated with each other in a young subject group to eliminate the effect of age. The peak frequency of mid-frequency heart rate fluctuations was significantly inversely related to age. The overall heart rate variability (0.01-.05 Hz) was reduced with aging due to the diminution of power spectral densities in the mid-frequency (0.05-0.15 Hz) and respiration related frequency band (heart rate spectral power around the mean respiratory rate). In the young subject group total power was positively related to the power of the discrete spectral components. The respiratory rate was inversely related to mid-frequency and respiration related frequency components of heart rate variability. Our results appear to support on the one hand the hypothesis of age-related alterations in the autonomic cardiovascular control mechanisms. On the other hand our data show significant correlations between spectral parameters of heart rate variability and respiration, which should be taken into consideration in the interpretation of heart rate power spectra in spontaneously breathing subjects. |
