Abstract
Electrophysiological activity can be mapped using sub-intervals of electrophsyiological signals. An electroanatomical mapping system receives a plurality of electrophsyiological signals (), each of which spans an activation interval. For each signal, the system identifies an initial event time within the activation interval, such as by identifying a time of maximum signal energy (), and defines a sub-interval about the initial event time (). The system then analyzes the sub-interval to identify one or more electrophysiological characteristics of the electrophysiological signal () and adds a corresponding electrophysiology data point to an electrophysiology map (). Advantageously, the sub-interval can extend outside of the activation interval, such that the instant teachings allow for capture and analysis of deflections that occur at or near the boundaries of the activation interval.
