Introduction Myocardial deformation (strain) analysis may be done through echocardiography from data obtained by tissue doppler technique or two-dimensional images from speckle tracking, allowing the calculation of longitudinal, circumferential and radial deformations of myocardial fibers., Myocardial strain analysis has recently been used in the evaluation of regional myocardial movement and function and in the systolic time-to-peak calculation which studies cardiac synchronicity and myocardial electromechanical coupling. In clinical practice, conventional echocardiographic investigation is helpful in detecting global myocardial dysfunction and alterations […]
