摘　　要：提出了一种采用脑电放大器实现BSPM的方案。方案采用两台64导联脑电放大器采集体表电位信号,通过零相位数字滤波器滤除干扰,最后结合导联布置位置和处理后的信号重构出BSPM。实验结果表明,提出的方案能够有效获取到与心脏电活动对应的BSPM。提出的方法在复杂心脏疾病诊断上具有巨大的潜力。An alternative method was proposed for generating BSPM by connecting two 64-lead electroencephalogram（ EEG） amplifiers in series for the collection of surface potential signals. A digital zero-phase bandpass filter was adopted to filter interference,and then the processed signals were used to reconstruct the BSPM according to the corresponding location of each lead. Experimental results show that the proposed scheme can effectively help obtain the BSPMs corresponding to the cardiac electrical activity. It indicates that the proposed approach has great potential in the diagnosis of complex cardiac diseases.
