Abstract
OLAYA, Pastor; SANCHEZ, Jairo and OSIO, Luis Fernando. Strain and strain rate for dummies. Rev. Colomb. Cardiol. [online]. 2011, vol.18, n.6, pp.340-344. ISSN 0120-5633.
Recent developments in the field of echocardiography have allowed cardiologists to objectively quantify regional and global myocardial function based on the deformation (strain) and strain rate which can be calculated non-invasively in both the left or right ventricle, and provide valuable information in multiple clinical settings. Since this new technique is promising and is being increasingly used in clinical and research studies, the adequate knowledge of its principles and its technical aspects, scope and limitations are necessary for its better implementation. This article seeks to explain fundamental concepts and potential clinical applications of strain and strain rate derived by speckle tracking (2D strain).
Keywords : strain; strain rate; speckle tracking.
