摘　　要：应用子带滤波算法对25例海洛因成瘾者和25例正常人进行对比分析，提取出海洛因成瘾者和正常人的HRV信号在特定频段上的能量均值特征向量及Shannon熵值，并对比其差异．为探索不同心率的交感一迷走神经的控制过程及临床应用提供新途径．By analyzing 25 cases of heroinaddicts and 25 cases of normal people, this paper adapts the method of sub-band filter to extract the feature vector of average of energy and Shaannon entropy value in specific bands of the above two groups of people, and finally draw out the differences. This method may serve as a new approach to exploring the control process and clinical application of sympathetic vs. vagus nerve of different heart rates.

关 键 词：心率变异性 子带滤波 能量均值 Shannon熵值
