Figure 2 Myocardial velocities at rest and peak dobutamine stress in the control group. The box plots display the 50th (H), 25th and 75th (  ), 10th and 90th (—) percentiles and circles for the <10th and >90th percentiles of the variable. There is a highly significant (***p < 0.001) increase for each of the measured peak velocities whereas the ratio of early to late diastolic velocities remained unchanged. VPRE = peak velocity during preejection period; VC = peak contraction velocity during left ventricular ejection; VE = peak velocity during early diastolic filling; VA = peak velocity during atrial contraction; VE/VA = ratio of early to late diastolic velocities.
