The identification and quantification of diffuse or global left ventricular (LV) hypokinesis is problematic. We investigate the feasibility of a novel technique called Center Point Trajectory (CPT) mapping that provides not only an improved method for identification of global hypokinesis but also a method for quantitatively characterizing diffuse left ventricular dysfunction. CPT mapping has an advantage in instances where the myocardial wall is thin, which is not uncommon in patients with underlying ischemic heart disease and heart failure.
