1. A method, comprising:
generating cardiac ultrasound images from ultrasound imaging data of a heart;
determining strain values at each portion of myocardium in the cardiac ultrasound images, wherein strain values are determined by contraction and elongation of the myocardium depicted in the cardiac ultrasound images;
generating a spatio-temporal map of electrical impulses in the heart from the strain values; and
outputting the spatio-temporal map of the electrical impulses in the heart to a display device, wherein the spatio-temporal map represents an electrical conduction pathway through the heart that is generated from the strain values;
wherein the spatio-temporal map is an animation of the heart made by adjusting a pre-made heart animation according to the strain values and a heart rate observed in the ultrasound imaging data of the heart.
