Abstract:ObjectiveTo discuss the relationship between blood pressure instant variability(BPIV) and heart rate variability(HRV) of human under respiratory control. MethodsFiftytwo healthy people′s ECG, blood pressure (BP)and respiration were synchronously recorded and analyzed when respiratory rate were controlled at 51015 times/min and 81216 times/min. ResultsAt respiratory rate of 1015 times/min and 81216 times/min, RR variation trend and BPBP variation trend were fully synchronized with respiratory wave variation trend. Correlation coefficients(r) of center frequency of RF/HR with peak of respiratory(RSP), BPIV and HRV were 0.924, 0.902 and 0.913, respectively. At respiratory rate of 5 times/min, RR variation trend and BPBP variation trend were desynchronized. ConclusionsAt certain respiratory rate, BPIV is corresponded with the physiological mechanism of respiratory sinus arrhythmia and HRV mechanism caused by respiratory sinus arrhythmia. However, BPIV is not corresponded with the physiological mechanism of HRV mechanism caused by respiratory sinus arrhythmia when respiratory rate is too low.
