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

Abstract
The present invention includes a method and apparatus for digital to analog conversion and reconstruction of multichannel electrocardiograms. The method may include receiving digital information representative of a plurality of independent signals, producing a plurality of analog outputs from said digital information wherein a first analog output is designated as a common reference, and imposing a predetermined voltage on a second analog output with respect to said common reference, which provides for a substantial recreation of the original independent signals. The apparatus may comprise a processor operable for receiving digital information representative of independent lead signals from a first ECG machine and digital to analog circuitry for substantially reproducing the original lead signals for analysis on a second ECG machine for convenient and efficient second opinions of cardiac data.
