摘要
A system includes a display device configured to present an epicardial vascular map. The system also includes a processing unit configured to: receive electrical signals obtained from a vascular mapping catheter and/or a magnetically tracked catheter; determine, from the electrical signals, a plurality of impedance measurements associated with one or more electrodes of the vascular mapping catheter; access a field map, the field map having expected impedance measurements determined based on determined positions of the one or more additional electrodes of the magnetically tracked catheter; determine, based on the plurality of impedance measurements and the field map, positions of the electrodes of the vascular mapping catheter; generate, based on the positions, the epicardial vascular structure; access the epicardial cardiac map; annotate the epicardial cardiac map with the representation of the epicardial vascular structure to generate the epicardial vascular map; and facilitate display of the epicardial vascular map.
