                 localize the region of stenosis when the patients are
                 exercised. The method is the same as I saw there in
                 1987 with the Karhunun Loeve Transform applied to the
                 data to extract the first two coefficients, which
                 locate a point on the plane of these coefficients. The
                 location can be correlated with the vessel which is the
                 most narrowed. The method came out of PTCA recordings.
