| 摘 要： | 在心电信号的分析中,QRS波群快速准确地检测是计算其他相关参数的前提.在正确识别R波的前提下,对心电信号进行频域变换后,以R渡点为基点,通过逐次计算R波左侧或右侧相邻两点的斜率并比较斜率是否发生突变,当相邻两点斜率突然发生变化时,可判断为Q波或S波.采用实时采集数据对以上算法进行验证,实验表明,该算法原理简单,计算量小,能够快速准确地检测心电信号数据中Q,S波的特征值.

| Abstract: | During the analysis process of electrocardiogram(ECG) signal, the premise of calculating other relevant parameters in ECG is based on detection of QRS wave. In this paper, the ECG signal identifies R-wave correctly and transforms frequency domain on the left of R-wave or on the right of R-wave, and calculates the slope of adjacent points and compares whether there is a sudden change of the slope in turns. When sudden change of the slope occurs, we can conclude that the wave is Q-wave or S-wave. The algorithm is validated by using the data. This experiment shows that the algorithm can firstly and efficiently detect the eigenvalue of Q-wave or S-wave in ECG database. |
