Is Tau dispensable?

Left ventricular diastolic time constant, Tau is the most established index to describe diastolic function. A Harvard method of Tau was invented by Dr JD Thomas has been dominant non-invasive Tau measurement for more than two decades. Now, Tau is dead clinically. Only when the logically flawed celebrity method is objectively reassessed and discarded, can Tau be given a chance. A new method is dawning and promising…

A Brief History of Tau

1976, Tau was born in John Hopkins.
1992, the first non-invasive try, Harvard.
1992, the first formula, with four assumptions, Harvard.
1993, another non-invasive try with decent data, Mayo Clinic.
1995, a similar strategy applied to AI patients, Japan.
1995, I published a MR based formula with one assumption.
1997, the Harvard formula was validated in Cleveland.
2005, Langer presented a non-zero asymptote model.
2008, I improved my MR based formulas, without assumption.
2008, I did a similar deduction for AI based Tau.
2008, Chen developed program for my formulas, free download.
2008, my poster in ASE 19th Annual Scientific Sessions.
2009, my poster in CSE forum.
2009, DF guideline (ASE) recommended Harvard formula.
2009, I gave my opinion about the guideline recommendation.
2009, "Response to Bai" from guideline writing group. It motivated me to create this Blog.
2010, Dr Wang and me presented general Tau.

The 7th letter to Dr JD Thomas

Dear Dr Thomas,

This is the 7th letter to you. Because all the previous ones were ignored, it might be a good idea to go public.

Please formally address your Tau formula which is logically flawed in our opinion.

Verification of flawed theory needs manipulated data, which is a hot topic in the whole medical publishing industry right now.

Inspired by the recent American election, let’s give each other a chance by exchanging ideas.

We might be wrong, please show us the right way.

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.
