Popis:	Background 2D speckle tracking echocardiography (2DSTE) was proved to be accurate for the assessment of the RV function. However, normal values for RV strain refer mostly to 3- or 6-segment models, excluding the contribution of other RV walls to RV function. We analyze RV function by 2DSTE in a normal population, using parasternal two-(2C) and apical four-chamber (4C) RV views, and creating a new 12-segment model for a potential better definition of RV function. Methods We prospectively evaluated 100 normals using 2DE and STE. We assessed the RV systolic function from regional strain (basal, mid, and apical), and at the level of each wall: lateral (LS), septal (SS), inferior (IS), and anterior (AS), and also global strain for 4C (4CGS), and 2C (2CGS). Global systolic strain rate (SRs) was measured from 2C and 4C views. Diastolic function was assessed from early (SRe) and late global strain rate (SRl), for both views. Results A total of 70 healthy individuals (48±15 years, 34 men) were suitable for concomitant 4C and 2CRV analysis. Feasibility of the STE analysis was 87.8%. We found significantly lower SS by comparison with LS, AS, and IS (P
