摘要
心率变异性与血压变异性反映心血管系统自主神经的调制活动 ,近年研究已向多变量、多维、动态分析方向发展。心率与血压变异性的多变量系统辨识、时频分析及非线性动力学分析等技术方法 ,将在心血管疾病的危险性预报、病情评估。
Heart rate variability (HRV) and blood pressure variability (BPV) reflect the modulation activity of autonomic nervous system on cardiovascular function. There have been important advances in multi variate, multi dimensional and dynamic analysis of HRV and BPV during recent years. Modern signal processing methods, such as multi variate system identification, time frequency analysis and nonlinear dynamics analysis, could be adopted in the risk prediction, severity evaluation and therapeutic treatment assessment of cardiovascular diseases. These new methods might also be useful in special environmental medicine.
