本文探讨了应用统计非线性物理方法来阐明控制心率的潜在机制的可能性。特别是，通过使用滞后去趋势波动分析来研究 RR 间期动态中延迟的存在。结果表明，充血性心力衰竭（CHF）患者的压力反射反应延迟时间较长。讨论了慢性心力衰竭患者自主控制功能的严重延迟的一些影响。 (C) 2009 年美国物理研究所。 [DOI：10.1063/1.3152005]
This paper explores the possibility of applying statistical nonlinear physics methods to elucidate the underlying mechanisms controlling the heart rate. In particular, the presence of delays in RR interval dynamics is studied by using a lagged detrended fluctuation analysis. The results indicate that patients with congestive heart failure (CHF) have a prolonged time delay in the baroreflex response. Some implications of large delays for the functioning of autonomic control in subjects with CHF are discussed. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3152005]
