Device and method for digital-to-analog transformations and reconstructions of multi-channel electrocardiograms

An apparatus for recreating substantially original lead signals produced by placing a plurality of electrodes on a living creature, comprising:

• a processor operable for receiving digital information representative of a plurality of independent lead signals, wherein each of said plurality of independent lead signal represents at least one of a plurality of electrical potentials (i) between at least one pair of said plurality of electrodes placed on said living creature or (ii) between at least one individual electrode from said plurality of electrodes placed on said living creature and a predetermined reference comprising an electrical resultant or potential difference between two or more predetermined electrodes from said plurality of electrodes placed on a living creature;
• and
• digital to analog circuitry comprised of a plurality of analog outputs wherein said plurality of analog outputs is comprised of a first analog output designated as a common reference and a second analog output wherein a predetermined voltage is imposed on said second analog output, and wherein said substantially original lead signals comprise electrical potentials between said plurality of analog outputs.
