IDENTIFICATION OF SITES CORRESPONDING TO SUSPECTED ATRIAL FIBRILLATION TRIGGERS BASED ON CORRELATION OF SIGNALS FROM MULTIPLE ELECTRODES

Abstract

A composite correlation score associated with a selected spatial location in the heart is determined based on a plurality of individual correlation values, each of which is based on a correlation between a signal associated with a selected electrode positioned at the selected spatial location and a signal associated with another one of the plurality of electrodes when the selected electrode is positioned at the selected spatial location. Composite correlation scores associated other selected spatial locations in the heart are determined the same way. An electro-anatomical map of the heart is displayed which depicts information representative of the composite correlation score determined for the selected spatial locations, including information indicating that a spatial location is a suspected trigger of AF.
