A new method for evaluating the systolic displacement of the left ventricle profile is proposed. It rests on the definition of an intracardiac axis and the identification of equivalent points on cardiac end systolic and end diastolic silhouettes separately. Displacement is then evaluated by means of vector methods. The results in ten normal subjects are reported. Systolic displacement is visualized by means of maps, which reflect the geometric properties of left ventricle normal contraction.

Abstract
A new method for evaluating the systolic displacement of the left ventricle profile is proposed. It rests on the definition of an intracardiac axis and the identification of equivalent points on cardiac end systolic and end diastolic silhouettes separately. Displacement is then evaluated by means of vector methods. The results in ten normal subjects are reported. Systolic displacement is visualized by means of maps, which reflect the geometric properties of left ventricle normal contraction.
