Abstract

A method, apparatus and computer program product, the method comprising obtaining a first electrical signal from a catheter comprising a first electrode distally disposed thereon, when the catheter is inserted into a heart chamber of a heart and the first electrode does not touch a chamber wall; performing statistical analysis of the first electrical signal to obtain a first characteristic of the first electrical signal; obtaining a second electrical signal from the catheter, when a second electrode touches a point on the chamber wall; performing statistical analysis of the second electrical signal to obtain a second characteristic of the second electrical signal; determining a similarity measure between the first characteristic and the second characteristic; and subject to the similarity being below a predetermined threshold, indicating the region as potentially belonging to an arrhythmogenic region of the heart.
