A Small Step in Math, A True Stride in Cardiology

With the progress of Doppler and modern computer technology, I believe that only a few RBCs’ leaking will be needed to give us a much understandable and clear regurgitation curve. Theoretically, merely a short part of the curve is enough to calculate the Tau. As long as we are allowed to choose 3 points from within the definition field, we can use the updated formulas to proceed. Let’s assume the 3 points are a (va, ta), b (vb, tb) and c (vc, tc) from left to right. The updated formulas are:



It is a small step in mathematics, but a true stride in cardiac clinic.
