Abstract
Methods, apparatuses, and systems to differentiate adipose tissue from scar tissue are disclosed. One or more electrophysiology data points, each of which includes an electrophysiological signal associated with a tissue location that possesses certain signal characteristics, can be collected. An adipose tissue probability and/or a scar tissue probability can be computed using the characteristics of the electrophysiological signal, such as signal duration, signal amplitude, signal fractionation, and/or late potentials. The probability computation can also utilize dielectric properties, such as tissue impedance, tissue conductivity, and/or tissue permittivity, measured at the tissue location. Graphical representations of the adipose tissue probability and/or scar tissue probability can also be output.
