Original Article Ribeiro et al. Simplified method to assess diastolic function by CMR Arq Bras Cardiol. 2020; 114(2):284-292 Figure 2 – Atrioventricular junction (AVJ) displacement-versus-time plot of the normal controls. AVJ position at multiple time points during the cardiac cycle. Error bars represent one standard deviation above and below the mean. MD: maximum displacement; MVED: maximum velocity early diastole; VDS: velocity in diastasis.
