针对心电图ST段检测精确度不高的问题,依据小波变换理论,提出了一种心电图ST段检测方法,检测心电图的特征值来准确确定J点及T波起点,并结合传统J+X法及T波起点检测方法达到准确检测ST段电位的目的。该方法通过M IT-B IH的STDB数据库和European ST-T数据库进行检验,ST段检测误差在4ms内的占94.5%,在8ms的占98.9%,提高了检测精确度。
According to the theory of wavelet transform, an ST-segment electrocardiogram detection method is proposed to detect the eigenvalues of ECG to accurately determine the starting point of J-point and T-wave. Combined with the traditional J + X method and T wave starting point detection method to achieve the purpose of accurate detection of ST segment potential. The method was tested by ST IT database and European ST-T database of MIT-B IH. The detection error of ST segment accounted for 94.5% in 4ms and 98.9% in 8ms, which improved the detection accuracy.
