StDti
I have the following in an echocardiography summary in a hospitalization report:
"Ventricule droit non dilaté, normokinétique (StDti = 11.8 cm/s). TAPSE 19 mm"
Could it be a typo for STDVD = RVEDV?
Thanks

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

3.3.3.6 Tissue Doppler imaging for right ventricular function
Longitudinal function of the right ventricle can also be assessed with tissue Doppler. This is done by placing the sample volume at the base of the free right ventricular wall. The spectrum looks quite similar to that of the left ventricle. However, in normal individuals the systolic deflection (S) is usually somewhat higher. The maximal velocity of "S" represents longitudinal right ventricular function. The lower limit of normal is 10 cm/sec.
