Strain and strain rate echocardiography
Current Opinion in Cardiology, 2002Strain and strain rate echocardiography is an emerging technique for assessing myocardial systolic and diastolic function. It is envisioned that this modality could change the quantitative assessment of regional wall motion and improve the accuracy and reproducibility of test readings. Myocardial strain and strain rate can detect inducible ischemia and

Eulerian strain-rate as a rate of logarithmic strain
Mechanics Research Communications, 1995It is pointed out that the deformation rate or the symmetric part of the velocity gradient can be interpreted as a real time derivative of a strain in a suitable rotating frame. Using principal axes, the authors determine the angular velocity of the frame and apply the general considerations to the special case of simple shear deformation.

Strain and Strain Rate Imaging in Cardiomyopathy
Echocardiography, 2009The most common indication for an echocardiogram is for the assessment of left ventricular (LV) function and, in the evaluation of cardiomyopathy (CM), this becomes even more important. However, conventional echocardiographic measures of ventricular function are insensitive at detecting subtle perturbations in contractility.

Heart Rate Effects on Strain and Strain Rate in Healthy Children
Journal of the American Society of Echocardiography, 2005Based on myocardial Doppler echocardiography, regional strain (S) and strain rate (SR) can be evaluated as regional parameters of ventricular function. The use of these techniques in clinical pediatric cardiology remains a challenge. This study establishes reference values for S and SR in both systole and diastole in healthy children over a large age ...

Strain-rate effects for high-strain-rate computations
Journal de Physique IV (Proceedings), 2006This paper examines the effect of strain rates for computations involving high strain-rates, beyond 10 3 s -1 . Although it is generally agreed that there is an enhanced rate effect at these higher rates, there is uncertainty regarding the interpretation of dynamic test data, the form of the high-rate effect, and the effect of the high rates on ...

Clinical Utility of Echocardiographic Strain and Strain Rate Measurements
Current Cardiology Reports, 2021Assessment of left ventricular function is pivotal in many decisions, but ejection fraction has fundamental limitations for assessment of mild dysfunction, and especially for repeated assessments. Myocardial deformation imaging using speckle-tracking is widely available on modern echocardiography systems, and is now feasible as a clinical, rather than ...
