1. An anatomical mapping system comprising: a plurality of mapping electrodes configured to detect electrical activation signals of intrinsic physiological activity within an anatomical structure; a plurality of mechanical sensors configured to detect mechanical activity associated with the intrinsic physiological activity; and a mapping processor associated with the plurality of mapping electrodes and mechanical sensors, the mapping processor configured to record the detected activation signals and associate one of the plurality of mapping electrodes and mechanical sensors with each recorded activation signal, the mapping processor further configured to determine activation times of the intrinsic physiological activity based on a correlation of corresponding electrical activation signals and mechanical activity.
