Web1 de fev. de 2013 · There is no current consensus on normal values of GCS and GRS, and our study is the first to define normal values of these parameters on the basis of a meta-analysis. These findings show that confidence intervals for GCS are similar to those for GLS, but inferior results were obtained for GRS. Directional Components of Strain
WebBackground: Normal range values of right atrial (RA) phasic function markers are essential for the identification of normal and abnormal values, comparison with reference values, and the clinical meaning of obtained values. Accordingly, we aimed to define the normal range values of RA phasic function markers obtained by 2D speckle-tracking … Web18 de dez. de 2024 · Aims: Left atrial (LA) function assessed by two-dimensional speckle-tracking echocardiography has shown increasing clinical and prognostic significance. We sought to establish age- and sex-based normative values of LA strain in the general population and to assess the prognostic yield of lower limits of normality of LA strain in …
