The medical imaging scan may provide a plurality of values of a predefined myocardial deformation parameter of said part of the myocardium. In a preferred embodiment the method comprises the steps of 1) determining a myocardial deformation deviation between pairs of myocardial deformation parameter values selected from the myocardium of substantially opposite 10 parts of a cardiac chamber, and 2) calculating the cardiac dyssynchrony of the subject based on said myocardial deformation deviation.1 /12 wall Anterosepta -0.25 -0.14 -0.08 0 0.12 0.16 Apex -0.25 -0.14 -0.09 0 0.12 0.19 -0.25 -0.14 -0.09 0 0.12 0.18 Inferolateral -0-25 -0.19 -0.09 0 0.13 0.18 wall -0.25_-0.14 -009 0 0.12 0.18 -0.25 -0.14 -0.08 0 0.12 0.18 Strain rate, 1/s Start-systole End-systole Fig. 1
