Strain and strain rate are new echo parameters of regional myocardial function.

2004 JUL 19 - (NewsRx.com & NewsRx.net) -- Strain and strain rate data as determined by echocardiography is a technique for detecting regional myocardiac ischemia.

According to a study from Germany, "Strain (deformation) and strain rate (velocity of deformation) are parameters of regional myocardial function which can be calculated at the bedside from tissue Doppler echo cardiographic data."

"These parameters are less image quality dependent and less subjective than visual assessment of endocardial border motion, and they track myocardial deformation with a considerably higher time resolution than magnetic resonance imaging. Thus, the technique can document …
