Delivering ablation therapy in a heart chamber

摘要

A method of delivering ablation therapy in a heart chamber includes inserting a catheter in the heart chamber. Electrophysiological data in the heart chamber is acquired with the catheter. The position of the catheter is determined using an electromagnetic field source external to the heart chamber, and the location of the acquired electrophysiological data is determined using the position of the catheter. The acquired electrophysiological data is integrated with the location of the acquired electrophysiological data. Information related to the three-dimensional geometry of at least a portion of the heart chamber is received. A continuous three-dimensional color-coded map of the electrophysiological data is created and superimposed on a geometrical representation of the three-dimensional geometry information. The map is then utilized to deliver ablation therapy.
