All participating investigators reported the requested variables from ten arbitrarily chosen exercise anxiety tests. Intraclass correlation coefficients (ICC) were computed to judge the inter-observer agreement utilizing the core laboratory. Inter-observer variability of resting and peak exercise tricuspid regurgitation velocity (TRV), right ventricular outflow area acceleration time (RVOT Act), tricuspid annular plane systolic excursion (TAPSE), tissue Doppler tricuspid horizontal ann
