Abstract
A method for mapping atrial fibrillation (AF) in a heart, the method includes receiving an electrogram (EGM) signal, which is acquired at a given position in the heart, and is exhibiting the AF. Two or more primary peaks are identified in the EGM signal, and a cycle length (CL) is calculated between adjacent primary peaks. One or more secondary peaks are identified in the EGM signal within the CL. A local fragmentation index (FI) that is indicative of a number of the secondary peaks per CL, is calculated. The local FI is visualized on a map of at least part of the heart.
