Abstract

Electrical activity is sensed from a plurality of electrodes of a multi-electrode catheter. For each of a plurality of surface locations of cardiac tissue, a processor identifies first electrical signals originating at a first depth and second electrical signals originating at a second depth, estimates a first near-field signal originating at the first depth for each of the first electrical signals and detects scar borders at the first depth based on the first near-field signals, and estimates a second near-field signal originating at the second depth for each of the second electrical signals and detects scar borders at the second depth based on the second near-field signals. Based on the scar borders detected at the first and second depths, the processor visually displays first and second maps of the heart depicting scar tissue at the first and second depths, respectively.
