Abstract
In clinical electrophysiological studies the information extracted from measured electrograms is mainly limited to the timing of local depolarization. We investigated the relation between the activation recovery interval (ARI) and electrogram waveform morphology in 3D structures. Of the various features extracted from simulated electrograms on the surface bounding the myocardium the integrals over a time interval around local depolarization showed the highest correlation with nearby ARI values.
