Using a noninvasive index of local segmental electromechanical delay in the eevaluation of left ventricular myocardium dyssynchrony

In this work we developed a new noninvasive index of local segmental electromechanical delay by the simultaneous use of electrical, mechanical and anatomical data obtained from Vector-Electrocardiography (VCG), Speckle Tracking Echocardiography (STE), Computer Tomography (CT) Imaging respectively, in order to provide a better characterization of electromechanical coupling in the left ventricle. This index could be useful to select patients for Cardiac Resynchronization Therapy (CRT) and for the assessment of its effectiveness.
