Abstract

Oscillations of heart rate and blood pressure are related to the activity of the underlying control mechanism. They have been investigated mostly with linear methods in the time and frequency domains. Also, in recent years, many different nonlinear analysis methods have been applied for the evaluation of cardiovascular variability. This review presents the most commonly used nonlinear methods. Physiological understanding is obtained from various results from small animals.

摘要

心率和血压的振荡与潜在控制机制的活动有关。人们大多在时域和频域中用线性方法对它们进行了研究。此外，近年来，许多不同的非线性分析方法已被应用于评估心血管变异性。本综述介绍了最常用的非线性方法。从小动物的各种结果中获得了生理方面的认识。
