基于时域分析的心脉同步信号时差图提取方法研究

Research on Extraction Method of Jet Lag Figure of Heart Chakras Synchronized Signal Based on Time-Domain Analysis

提出了一种基于时域分析的,通过阈值计算得出单周期信号并计算心电、脉象信号时差值的方法。将中医脉诊信息通过计算机采集得到脉搏数据,对比心电图数据进行分析计算,得出同一射血周期内的血液传播时间,并逐点描绘成图。此方法较传统方法具有可定量计算等明显优势,是中医诊断现代化的一种新的方法,在生物医学工程领域应具有有良好的应用空间和研究价值。

We propose a method which is based on the analysis of time domain. Through the calculation of the threshold, we can get the single periodic signal with which we can figure out the jet lag value between ECG signal and pulse signal. We get pulse data through the computer data acquisition. In the process of the comparison between pulse data and ECG data and quantitative analysis, we work out the travel time of blood in the same ejection cycle which can form a diagram. This method which has an obvious advantage that it can be quantitatively calculated,is one that modernizes TCM diagnosis and will have good application and research value in the area of biomedical engineering.
