Abstract The two-dimensional speckle tracking echocardiography can track the speckle echo of cardiac tissue to obtain the global and regional deformation parameters of myocardium. Compared with other small rodents, rabbit hearts have a comparative advantage in the evaluation of structure and function. Among the application fields, ischemic heart disease rabbit models are the most widely used. Other fields, such as hypertensive ventricular hypertrophy, hyperthyroidism cardiomyopathy and hypercholesterolemia, trauma, infection induced myocardial damage have also been studied. This paper reviews the principle of two-dimensional speckle tracking technology, the advantages and disadvantages of the rabbit models and the application of speckle tracking in the rabbit models, so as to provide reference for preclinical experimental study.
