Abstract
In an implantable antiarryhythmia pacemaker, an automatic cardiac arrhythmia detection and classification monitoring apparatus and method for measuring stimulated intracardiac electrogram potentials, deriving therefrom a paced depolarization integral (PDI), analyzing time-based changes in the PDI, detecting and classifying harmful cardiac rhythms while distinguishing harmful from benign tachycardias, and automatically establishing and initiating an appropriate therapy, if necessary, to revert the arrhythmia condition.
