摘要 表面拉普拉斯是一种高空间分辨率的体表势分析方法。我们介绍一种集信号调理与新的三电极同心圆环传感电极于一体的表面拉普拉斯传感器,并将其用于体表拉普拉斯心电的直接测量。采用一种新的非线性自适应算法检出信号中包含的工频干扰信号的频率、幅度和相位,以消除工频干扰的影响,并采用小波收缩技术消除其他噪声的干扰,得到了比较满意的测量结果。为该测量方法的进一步临床应用奠定了基础。 Surface Laplacian of the body surface potential （Laplacian ECG--LECG） is a new approach to resolve spatially distributed bioelectrical source. In this paper, we discussed an LECG sensor which integrated triple concentric ring electrodes and signal adjustor on a printed board. The LECG is measured directly by this sensor, The frequency, amplitude and phase of the power line interference were detected by a nonlinear adaptive filter so that interference was eliminated. The wavelet shrinking technique was used to eliminate the rest of random noise, And we got the high quality LECG signal. It laid the foundation for heart disease diagnosis.
