a method for monitoring left ventricular myocardial wall thickness . the method includes : obtaining real time images of a periodically spatially changing myocardium and segmenting the myocardium in such images ; calculating wall thickness of the myocardium from each one of the obtained images ; and performing a dynamic harmonic analysis of the calculated thickness to determine spatial changes in the thickness of the wall of the myocardium . the method applies the calculated wall thickness to a predictor to determine changes in the thickness of the wall of the myocardium . the method applies the calculated wall thickness to a predictor to determine the periodicity the myocardium .
