Two-dimensional (2D) speckle tracking echocardiography (STE) is a new tool for evaluation of LA function. The aims of this study are to establish the normal range of LA function measured by 2DSTE in different age groups and to evaluate the relations between the parameters of 2DSTE and Doppler echoca...
