Abstract: A new and superior strategy for analyzing electrocardiograms (ECG) is disclosed. The strategy utilizes standard leads obtained from only limb electrodes from a conventional electrocardiography system. The strategy determines new additional leads which are utilized in a new calculation of values which upon appropriate analysis, provide new information as to electrical fluctuations in the heart. Also disclosed are processes for mapping and transposing the values in digital form and optionally upon a three-dimensional heart model. And, related systems and computer-readable media are disclosed for performing these processes.
