3 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).

4 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.

5 Fig. 4 The ankle pressure index at rest in 30 patients before and after treatment. The results are presented as median and 90% tolerance levels (90% range). p > 0.05, Wilcoxon rank sum test.

6 Fig. 5 The ankle pressure index 30 seconds after the end of exercise in 30 patients before and after treatment. The results are presented as median and 90% tolerance levels (90% range). p < 0.01, Wilcoxon rank sum test.

7 Fig. 6 The recovery time in 30 patients before and after treatment. The results are presented as median and 90% tolerance levels (90% range). p < 0.01, Wilcoxon rank sum test.

8 Fig. 7 The percentage change in stroke distance (%Δ Sd) in 30 patients before and after treatment. The results are presented as median and 90% tolerance levels (90% range). p < 0.01, Wilcoxon rank sum test.
