Figure 2: Tissue Doppler velocity curve in a healthy volunteer. Apical 4-chamber view. The sample volume is positioned in the basal inferior septum. The initial positive excursion represents the isovolaemic contraction phase (IVC), followed by the systole. The negative waves represent early (E') and late (A') diastole.

Figure 3a-b: a) TDI-velocity curves in a patient with ischaemic cardiomyopathy. In contrast to Fig. 2 there is reduced velocity (3.8 cm/s) at rest due to hypokinesis in the inferior basal septum. b) During peak dobutamine stress there is a significant increase up to approximately 10 cm/s, indicating contractile reserve. Note the reversal of E'/A' indicating diastolic dysfunction.
