Electrocardiogram　(ECG)　and　Vectorcardiogram　(VCG)　are　essential　in　diagnosing　heart　diseases.　Combining　both　VCG　and　ECG　signals　can　significantly　improve　the　accuracy　of　heart　disease　diagnosis.　However,　due　to　the　intricacy　of　the　devices　and　the　additional　leads　required　to　be　placed　on　the　patient,　it　is　inconvenient　to　capture　these　two　signals　simultaneously.　To　obtain　both　signals　at　once,　this　work　presents　a　U-Net　network　that　integrates　residual　blocks　and　gate　attention　mechanisms　to　convert　VCG　signals　into　12-lead　ECG　signals.　The　experimental　results　demonstrate　a　high　degree　of　similarity　between　the　12-lead　ECG　signals　derived　from　the　proposed　approach　and　the　original　12-lead　signals.　©　2024　Copyright　held　by　the　owner/author(s).
