There are different ways to measure the regional function of the wall. It has been proposed to measure the speed of the LV wall motion, the thickening of the wall, or other changes in the shape of small regions of the wall as it contracts and relaxes. The latter is best measured using the mechanical quantity called “strain." Strain can be described as the percentile change in spacing between two points on a deforming object.
