Bland-Altman plot for conventional myocardial performance index (MPI) and myocardial performance index by tissue Doppler. Bland-Altman plot for conventional myocardial performance index (MPI) by pulsed wave Doppler and myocardial performance index by tissue Doppler TDMPI of right ventricle (upper left) and left ventricle (lower left) in the athletes group and the right ventricle (upper right) and left ventricle (lower left) in the sedentary group. The mean value of the two methods is displayed on the x-axis and the difference between the methods is displayed on the y-axis. The two dotted lines represent a 95% confidence interval and the solid line represents the mean difference between the measurements
