The feasibility of using echocardiography to identify stress induced wall motion abnormalities was first demonstrated with M-mode recordings. The practical use of such a test had to await the development of 2-dimensional echocardiography whereby more wall segments could be analyzed. From the early days of 2-dimensional echocardiography there have been a succession of technological and clinical advances which have made stress echocardiography a very clinically useful tool in the management of patients with known or suspected coronary artery disease. These developments included the realization that stress-induced wall motion abnormalities produce stunned myocardium permitting immediate post-treadmill echoes to be clinically useful, the use of pharmacologic stress, the introduction of digital recording techniques so that rest and stress images could be viewed side-by- side, and more recently the advent of new imaging technologies, such as harmonic imaging of tissue to provide higher quality of stress echocardiograms.
