Fig. 2 Typical recordings by transcutaneous aortovelography (a) at rest and (b) at the end of standard exercise in a patient demonstrating an increase in Sd. Tf, Flow time; Pv, peak velocity; Sd, stroke distance (1/2; Pv × Tf).

Fig. 3 Typical recordings by transcutaneous aortovelography (a) at rest and (b) at the end of standard exercise in a patient with coronary artery disease. There is a decrease in Sd associated with ST segment depression on the ECG.
