Factor Analysis: Its Place in the Evaluation of Ventricular Regional Wall Motion Abnormalities



The detection and evaluation of regional wall motion abnormalities (RWMA) represents clinically relevant information. It is also increasingly important because the presence and extent of RWMA can guide the therapeutic approach and enable precise follow-up. As a consequence, there is a need to refine the methods of detection by improving the topographic localization of the abnormality as well as the evaluation of its extent and type (hypokinesia, akinesia, dyskinesia).
