The application discloses a kind of cardiac transmembrane potential imaging methods based on 12 lead electrocardiogram joint physiological model and attention mechanism, to solve the serious ill-conditioned problem caused by information asymmetry between 12 lead signal and TMP, reconstruct cardiac transmembrane potential from 12 lead ECG signal.In order to obtain the dynamic physiological information of BSP and TMP, the application introduces self-attention mechanism to capture the long-term, periodic dynamic activation process characteristics of cardiac electrophysiology, extract the similarity within the sequence, calculate the attention score, then multiply the score with the input sequence, extract the key segment in the sequence, i.e.the segment that is expected to be "noticed".Meanwhile, the application regards the inverse problem as the potential feature mapping of TMP on BSP, captures the dynamic characteristics of inverse relationship by introducing cross-attention module, learns the inverse feature mapping relationship from a large number of data pairs using neural network, and solves the ill-posed problem of inverse problem.
