Is Tau dispensable?

The heart provides energy to the circulation system. How powerful the muscle is played a key role in terms of cardiac function assessment. Tau is directly related to the active relaxation of the left ventricle, no alternatives so far.

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.
2011-11-29, I gave a talk in National Capital Echo Round (Ottawa)
2016-03-29, I gave a talk at the Heart Institute, the North Hospital (Shenyang, China)
2016-04-01, I gave a talk at the Cardiac Function Dept., the 1st Clinical College, Chinese University of Medicine. (Shenyang, China)
2016, Symmetry inspired by the approach of Tau.

Huawei at Crosshair, Walking Dead over the Shoulder

Recently, the US government raised the gun and aimed at Huawei again. This time, what makes it unique is the load is a fatal slug. Trigger pulled, the bullet is flying. 

Is Huawei the walking dead?

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.

Questions Need to be Clarified...


  • Why not publish your paper in high AF journals?

Honestly, we tried a lot and most are failed. There is a dominant Tau non-invasive method from Harvard. Though the method doesn’t make sense, it made quite a few Tau “experts” who are always there to kill our papers. It is so easy for them to do so because they are influential researchers from influential institutions and they have already published their papers in influential journals. That is why we are calling for the retraction of these Tau papers with logic flaws. Before the retraction of fake ones, it is very tough for real ones to be accepted in high AF journals.

Dr James Thomas, Please Retract Your Tau Papers


According to COPE (Committee on Publication Ethics)’s Retraction guidelines, your Tau papers should be retracted since your Tau formula was developed based on FOUR bold assumptions which inflicted at least two logic flaws:

The Good, the Bad and the Ugly


1993, Dr Nishimura put his hand on Tau.  In the Table 1 (Comparison of Catheter-Derived and Doppler-Derived Variables for 120 Beats in 15 Patients), his measurement is Tau=58ms, (v1-t3)=48ms. 15 years later, I published the Tau formula Tau=1.2(t1-t3). Here comes a miracle: 58=1.2x48. Dr Nishimura has to command the profound respect of us, how such an accurate measurement is possible! In the meantime, my formula is also validated objectively. Now this formula is integrated into Mindray’s Echo machines sold all over the world except North America. This is the Good.

Who Killed Tau?

Tau is the best index to describe diastolic function, however, this indispensible index can only be measured in a catheter lab.  In our daily clinic, it is dead. Who killed it?
