  • LATE ACTIVATION OF CARDIAC SIGNALS
    Publication number: 20220287615
    Abstract: In a described example, a method includes identifying, by a processor, negative deflections of at least one unipolar signal representing cardiac electrical activity on a surface of interest during a respective interval of the at least one signal. The method also includes determining, by a processor, an activation time for a last identified negative deflection in the respective interval. The method also includes detecting, by the processor, an instance of late activation based on comparing the activation time to a temporal threshold.

  • Mapping of complex fractionated atrial electrogram
    Patent number: 9629567
    Abstract: Software and apparatus are provided to automatically detect and map areas of complex fractionated electrograms within cardiac chambers. Electrogram signal are analyzed to count the number of complexes whose amplitude and peak-to-peak intervals meet certain criteria. Functional maps indicating average complex interval, shortest complex interval, and confidence levels are produced for display.
