Why the study?
What is the intraobserver reproducibility of two-dimensional ultrasound-derived strain imaging in healthy human hearts?
What is the intraobserver reproducibility of two-dimensional ultrasound-derived strain imaging in healthy human hearts?
Two-dimensional ultrasound-derived strain imaging shows good to excellent intraobserver reproducibility for peak strain indices in the LV, RV, and LA, though radial strain and strain rate are more variable.
