Electroanatomic mapping refers to the acquisition and display of electrical information combined with spatial
localization. Technologies presently available include both contact and noncontact
electroanatomic mapping. This review focuses on the creation and proper interpretation
of contact electroanatomic maps, which involves the sequential recording of unipolar
or bipolar electrograms with a catheter in contact with the endocardium or epicardium
and display of this information on a three-dimensional navigation system. These techniques
have become invaluable in the evaluation of complex arrhythmias by providing a spatial
catalogue of electrical information. This allows the user to define an area of interest
with greater resolution than is possible using fluoroscopy alone and to revisit sites
of interest that already have been catalogued.
