Intraobserver and Interobserver Reproducibility for Radial Circumferential and Longitudinal Strain Echocardiography

摘要

Objectives: Strain echocardiography (StE) promises to be a new tool for quantitative assessment of cardiac function. Analysis of intra- and interobserver reliability is an important aspect in the process of developing these novel techniques from theory to the implementation into daily routine diagnostics.The purpose of the study was to estimate reliability of the segmental StE.
