[Tissue Doppler in the assessment of myocardial function in stress echocardiography].

Recently, stress echocardiography has emerged as a valuable tool for the diagnosis and evaluation of coronary artery disease, but its interpretation still remains subjective, relying on image quality and reader's experience. These problems could be overcome by quantitative analysis of wall motion. Tissue Doppler provides quantitative information on regional myocardial systolic and diastolic velocities that can be displayed either in spectral...
