Abstract
Heart rate variability is assumed to result from a multiplicative or cascade mechanism based on its multifractal property. Numerical results on the perturbation of the cascade are given to compare HRV under parasympathetic (PNS) and sympathetic (SNS) autonomic blockades. It was found that qualitative change of the HRV multifractal, which was observed in PNS blockade, is due to the change from a multiplicative to an additive mechanism.
摘要
心率变异性基于其多重分形特性被认为是由乘法或级联机制产生的。给出了关于级联扰动的数值结果，以比较副交感神经（PNS）和交感神经（SNS）自主神经阻滞下的心率变异性。研究发现，在PNS阻滞中观察到的心率变异性多重分形的定性变化，是由于从乘法机制转变为加法机制所致。
