In the previous paper, we reported that exercise tests were performed on the basis of the brachiocephalic arterial flow with continuous wave Doppler echocardiography and changes in the peak flow velocity of blood were correlated with changes in the ejection fraction of the left ventricle. Since our approach is the continuous observation of changes in the arterial flow, the application of a personal computer is indispensable in order to analyze the vast data obtained. Therefore, by indicating on the display screen the signals of the brachiocephalic arterial flow continuously put out by the continuous wave Doppler flowmetry, during exercise, we have devoloped the software which automatically calculates the peak flow velocity. We also report having devised an evaluating system for exercise capacity which has the combined data of changes in the peak flow velocity, ST changes on the electrocardiogram and changes in heart rate, during exercise and in a recovery period.
