1. A method for quantifying myocardial kinetics comprising: positioning a first sensor and a second sensor on respective myocardial substrate sites on opposing sides of a ventricular wall so that the first sensor is opposing the second sensor along the ventricular wall; tracking a relative displacement between the first sensor and the second sensor; computing a wall thickening of the ventricular wall based on the tracked relative displacement; determining whether the myocardial substrate site includes an infarct based on the wall thickening; and determining if the infarct is located closer to the myocardial substrate site on an endocardium or to the myocardial substrate site on an epicardium.
