Tissue Doppler, speckling tracking and four-dimensional echocardiographic assessment of right ventricular function in children with dilated cardiomyopathy

Figure 3 Right ventricular global longitudinal strain measures of a healthy child from the standard four-apical views using two-Dimension speckle tracking method. The upper left quadrant shows tracking. The right half shows color-coded segmental strain curves and average strain curve (dashed line). The lower left quadrant depicts an anatomic M-mode. The dashed yellow line = Time to peak (from R-wave to maximum systolic strain.
