Fig 1 A trace of a transit time flow measurement analysis shows a normal diastolic dominant curve with its variables. PI = (Qmax − Qmin)/Qmean. (ACI = acoustic coupling index; BF = backward flow; LAD = left anterior descending artery; LIMA = left internal mammary artery; PI = pulsatility index; Qmax = maximum flow; Qmean = mean flow; Qmin = minimum flow.)
