Velocity tracking, a new and user independent method for detecting regional function of the left ventricle

Background:  The use of two‐dimensional echocardiography (2D echo) for detection of ischaemia is limited due to high user dependency. Longitudinal motion is sensitive for ischaemia and usable for quantitative measurement of longitudinal myocardial function but time consuming. Velocity tracking (VeT) is a new method that gives an easy three‐dimensional understanding of both systolic and diastolic regional motion, using colour coded bull’s eye presentation of longitudinal velocity, derived from colour coded tissue Doppler. The aim of this study was to test the accuracy of VeT in detecting ischaemia in non‐ST‐segment elevation myocardial infarction (NSTEMI) patients bedside.
