本程序是用经验模态分解(EMD)算法检测VF信号的，该算法的灵敏度和特异性都达到了90 以上。-This procedure is used empirical mode decomposition (EMD) algorithm to detect VF signals, the sensitivity and specificity of the algorithm has reached more than 90 .

用于解决EMD分解过程中存在的模态混叠问题，采用总体平均经验模态分解算法，同传统EMD相比，分解效果更好。(To solve the problem of modal aliasing existing in the EMD decomposition process, the total average empirical mode decomposition (EMD) algorithm is adopted, and the decomposition effect is better
