Summary:Electrophysiological activity can be mapped using sub-intervals of electrophysiological signals. An electroanatomical mapping system receives a plurality of electrophysiological signals (402), 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 (404), and defines a sub-interval about the initial event time (406). The system then analyzes the sub-interval to identify one or more electrophysiological characteristics of the electrophysiological signal (408) and adds a corresponding electrophysiology data point to an electrophysiology map (410). 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. 可以使用电生理信号的子区间来标测电生理活动。电解剖标测系统接收多个电生理信号(402)，每个电生理信号跨越一激活区间。对于每个信号，系统识别激活区间内的初始事件时间，例如通过识别最大信号能量的时间(404)，并定义围绕初始事件
