1. A method of digital to analog transformation for reconstruction of a first set of analog signals from digital information representative of said first set of analog signals wherein said digital information is generated by a first electrocardiogram (ECG) machine and wherein said reconstruction results in a second set of analog signals capable of use as an input into at least a second ECG machine, comprising the steps of:

  • receiving said digital information representative of said first set of analog signals and consisting of eight independent signals, wherein each independent signal represents at least one of a plurality of electrical potentials (i) between at least one pair of a plurality of electrodes placed on a living creature or (ii) between at least one individual electrode from said plurality of electrodes placed on said living creature and a predetermined reference;

    utilizing a digital-to-analog (DAC) device to produce said second set of analog signals comprising nine analog outputs from said digital information wherein a first analog output of said nine analog outputs is designated as a common reference;

    utilizing said DAC device to impose a predetermined voltage on a second analog output of said nine analog outputs with respect to said common reference; and

    utilizing said second set of analog signals as said input into said at least said second ECG machine,wherein said second set of analog signals represents a clinically sufficient approximation of said first set of analog signals.
