Advances in echocardiography mean that it is now possible to measure myocardial function accurately and non-invasively. Paradoxically, objective quantification of myocardial motion, contraction, and relaxation in each segment of the left ventricle actually makes it more difficult to define normality and disease in the individual patient, but the technique raises intriguing possibilities in population studies for diagnosing early heart muscle disease and testing new approaches to treatment.
The catalyst to this approach was the development of tissue Doppler echocardiography to measure the velocity of myocardial motion, and then the processing of digitally stored velocity data to obtain measurements of regional myocardial deformation (strain and strain rate). Machines do not apply the Doppler equation when processing these signals, and so an alternative and more accurate term that encompasses all available methods is myocardial velocity imaging.
