  • System, software, and method for detection of sleep-disordered breathing using an electrocardiogram
    Patent number: 7801593
    Abstract: A system to form and store an electrocardiogram (ECG) signal derived from a cardiac electrical signal that includes an apparatus having a pair of the electrodes to connect to a patient to detect the cardiac electrical signal. A signal sampler samples the cardiac electrical signal to form the ECG signal. A data storage device stores the ECG signal. A computer communicates with the data storage device to retrieve the ECG signal for analysis by software stored in the memory of the computer. The software analyzes a morphology of the amplitude of a plurality of R-wave peaks contained within the ECG signal and/or analyzes a morphology of the area of a plurality of QRS complex pulses contained within the ECG signal.
    Type: Grant

    Date of Patent: September 21, 2010
    Assignees: Board of Regents, The University of Texas System
    Inventors: Khosrow Behbehani, Sridhar Vijendra, John R. Burk, Edgar A. Lucas
