Figure 1From: Are measurements of systolic myocardial velocities and displacement with colour and spectral Tissue Doppler compatible? Typical LV longitudinal myocardial velocity curves (top) obtained with colour TD from the basal segment of septum ( insertion ). Integration of the velocity curves over time yielded the corresponding longitudinal myocardial displacement curves (bottom). Isovolumic contraction time (IVCT) and isovolumic relaxation time (IVRT) are indicated.Back to article page
