Method and apparatus for filtering electrocardiogram signals to remove bad cycle information and for use of physiologic signals determined from said filtered ECG signals



Method and apparatus for filtering electrocardiogram signals to remove bad cycle information and for use of physiologic signals determined from said filtered ECG signals



Official Gazette of the United States Patent and Trademark Office Patents 1238(1)



In using electrogram signals to determine physiologic conditions like ischemia, the bad cardiac cycle information due to noise, axis shifts in the cardiac electrical axis, and the like must be removed if the electrogram signal can be made to be a good indicator. If this is accomplished through the adaptive filtering techniques shown here, the signal can be used to drive a closed loop therapy system responsive to those physiologic conditions discernible from good cardiac cycle electrocardiogram signals.
