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.
