Atrial Fibrillation Clinical Trials

This is a cohort study to evaluate algorithms for mapping atrial fibrillation by mapping atrial structure and mapping electrical activity to detect physiologically important areas. A key innovation of the observation study is to assess tracking of physiological activity in AF, in relation to tissue activity (MAP recordings), and in relation to AF waves of activity. This observational work extends prior studies that focused on focal and rotational activity, dispersion of electrical activity, low voltage activity and others.
