| Description | The aim of the present study was to evaluate the role of respiration in the spectral method of BRS determination. We used the spectral method during breathing controlled by metronome at 0.33Hz in 118 healthy subjects. We compared a modulus between the cross-spectral density of variation of pulse intervals and systolic blood pressure (ms*mmHg) and the spectral density of variation of systolic blood pressure (mmHg*mmHg) at 0.1 Hz (BRS 0.1 Hz), and a modulus at 0.33 Hz (BRS 0.33 Hz). A statistically significant correlation was found between BRS 0.1 Hz and BRS 0.33 Hz (r = 0.52, p<0.001). The ratio of BRS 0.1 Hz to BRS 0.33 Hz (0.876+-0.419) was significantly lower than 1 (p<0.01). |
