Digital-to-Analog Transformation and Reconstruction of ECG Data

The innovators at NASA Johnson Space Center have developed a new method and device for specialized digital-to-analog conversion (DAC) and reconstruction of multichannel electrocardiograms (ECGs), including 12-lead ECGs. Current devices do not have the functionality that allows for the transmission of stored digital ECG data collected from one manufacturer’s ECG machine to another for an automated second opinion. With this technology, the physician has the opportunity to compare results by transferring the ECG data to another ECG machine — regardless of location — when a patient’s results are difficult to interpret for a second opinion. The technology also allows for the use of less expensive 12-lead ECG front ends or analog-to-digital conversion (ADC) hardware that is advantageous when in remote locations or with patients who are mobile during research studies. The digital-to-analog transformation and reconstruction of ECG data technology is available for licensing.
