3-D display method for electrocardiogram

A 3-D display method for electrocardiogram includes the following steps:1) Obtain plural electrocardiogram signals from the body; 2) Define a 3-D orthogonal coordinate system in which the three axes represent the amplitude, the time, and the sensor location of the electrocardiogram respectively; 3) Define an amplitude display table that projects different amplitudes into different visual ways; 4) Utilize the digitized plural electrocardiogram signals to depict the 3-D diagram according to the coordinate system in step (2) and the table defined in step (3); 5) Show the 3-D diagram on a display terminal.
