1. A computer implemented method for generating an image map of an organ identifying portions of the organ which are viable and have reduced nervous control, comprising:
- receiving a first image of the organ, wherein the first image indicates viability of the organ;
receiving a second image of the organ, wherein the second image indicates nervous control of the organ;
identifying, using a data processor, portions of the organ, each being indicated in the first image to be viable, and indicated in the second image to have a level of nervous control below a predetermined threshold or below normal control levels; and
generating, using the data processor, an image map of the organ indicating said identified portions.

Abstract
A method of treating cardiac arrhythmia in a heart, including (i) determining that cardiac tissue is viable but with reduced innervation; and (ii) ablating the tissue to reduce a prevalence of arrhythmia in said heart. Optionally, the determining comprises detecting portions of heart wall which lack electrical activity. Optionally, at least some tissue which is viable but lacks nervous control is ablated, for example, to reduce or avoid arrhythmia.
