A method of determining baroreceptor reflex sensitivity is proposed that is based on spectral analysis of systolic pressure values and RR interval times, namely, the modulus (or gain) in the mid frequency band (0.07-0.14 Hz) between these two signals. Results using this method were highly correlated (0.94; n = 8) with results of the phenylephrine method. In addition, compared with the values for the preceding rest period, the modulus decreased during mental challenge, as might be expected from the literature.
提出了一种基于收缩压值和RR间期时间的频谱分析来确定压力感受器反射敏感性的方法,即这两个信号在中频带(0.07 - 0.14 Hz)的模量(或增益)。使用该方法得到的结果与去氧肾上腺素方法的结果高度相关(0.94;n = 8)。此外,与之前休息期的值相比,在精神应激期间模量降低,正如文献中所预期的那样。
