a memory storing computer readable instructions that, when executed, cause the processor to perform operations of the method as previously described.

For example, the computer readable instructions, when executed, cause the one or more processors to: collecting three-lead electrocardio signals LA, RA and LL of a collected object; processing the three-lead electrocardio LA, RA and LL signals to obtain three-lead electrocardio RL signals; processing the three-lead electrocardio signals LA, RA, LL and RL to obtain electrocardio data; generating six-lead data based on the electrocardio data; inputting the six-derivative data into a trained electrocardiogram generating model to obtain an electrocardiogram of the acquired object.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned. Furthermore, it is obvious that the word "comprising" does not exclude other elements or steps, and the singular does not exclude the plural. A plurality of units or means recited in the apparatus claims may also be implemented by one unit or means in software and/or hardware. The terms first, second, etc. are used to denote names, but not any particular order.
