3D Cardiac Imaging of Electromechanical Coupling

A novel method for three dimensional (3D) electromechanical mapping of the heart is presented. The new method is based on utilizing special magnetically locatable catheters connected to a mapping and navigation system. The 3D electromechanical map of the chamber is reconstructed by sampling the location of the catheter tip throughout the cardiac cycle at a plurality of endocardial sites together with their local electrograms. The ability to spatially combine electrical and mechanical information may provide a useful tool for both research and clinical cardiology.
