The Harvard Method of Tau Papers Should be Retracted

The Harvard method was invented in 1992 by Dr James Thomas from Harvard and got a brief experimental verification.

Not Only Tau

Tau renders us a new approach to the cardiac function assessment. Since Tau is directly related to how powerful the muscle is at the beginning of diastole, it is well accepted as the best index to describe diastolic function.

Anversa Opened a Wrong Door, Thomas Closed a Right Door

When I read The Emperor’s New Clothes as a kid, I did not take it seriously. Funny though, I did not think it would ever happen for that was just the adults’ wild imagination to fool the kids around. After growing up, I realized this can truly happen in the adults’ world. Jaw droppingly, smart and decent people are usually involved.

Non-invasive measurement of left ventricular diastolic time constant (Tau)

Mindray had just launched a high-end ultrasound machine DC80, which is the first Tau-measurable ultrasound machine in the world.

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 (v_a, t_a), b (v_b, t_b) and c (v_c, t_c) from left to right. The updated formulas are:
