随着近年来现代电子技术与数字计算机技术的飞跃发展和对心电信号信息的深入研究,对心电监护设备和心电信号分析算法程序的要求也越来越高,然而都需要有一个权威的心电图检测标准,来衡量其性能的好坏。本文以MIT-BIH心电数据库作为研究对象,首先对心电信号进行了小波去噪,然后对ECG信号在基于小波变换和阈值分析技术上对R波进行了检测,最后对Q、S波检测,且进行了合理修正,并在心电信号上给予了标定。较准确的检测了QRS波群的相关信息,效果良好。,
With the rapid development of modern electronic technology and digital computer technology in recent years and the further study on the information of ECG signals, the requirements on ECG monitoring equipment and ECG signal analysis algorithm programs are also getting higher and higher, however, all need to have an authority ECG test to measure the performance of good or bad. In this paper, MIT-BIH ECG database as the research object, the first ECG signal wavelet denoising, and then on the ECG signal based on wavelet transform and threshold analysis of R wave detection technology, and finally Q, S wave detection , And made a reasonable correction, and given in the ECG signal calibration. More accurate detection of QRS wave group related information, the effect is good. ,
