System and methods for electrical-anatomical imaging of the heart

Noncontact, multielectrode catheter mapping derives single-beat endocardial activation, while intracardiac echocardiography constructs detailed three-dimensional endocardial anatomy. The study tested the feasibility of integrating both modalities in a single system that enabled beat-by-beat electrical-anatomical imaging. It was found that integrating intracardiac echocardiography with noncontact mapping was feasible and provided detailed, single-beat, three-dimensional electrical-anatomical images that could facilitate diagnosis of arrhythmias and advance their therapy.
