  • Real-time, high frequency QRS electrocardiograph with reduced amplitude zone detection
    Patent number: 7539535
    Abstract: Real time cardiac electrical data are received from a patient, manipulated to determine various useful aspects of the ECG signal, and displayed in real time in a useful form on a computer screen or monitor. The monitor displays the high frequency data from the QRS complex in units of microvolts, juxtaposed with a display of conventional ECG data in units of millivolts or microvolts. The high frequency data are analyzed for their root mean square (RMS) voltage values and the discrete RMS values and related parameters are displayed in real time. The high frequency data from the QRS complex are analyzed with imbedded algorithms to determine the presence or absence of reduced amplitude zones, referred to herein as “RAZs”. RAZs are displayed as “go, no-go” signals on the computer monitor. The RMS and related values of the high frequency components are displayed as time varying signals, and the presence or absence of RAZs may be similarly displayed over time.
    Type: Grant
    Filed: January 26, 2006
    Date of Patent: May 26, 2009
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
