[Stress-exercise echocardiography].

The authors review the methodology and clinical applications of exercise echocardiography. This is a method that can be done in most of the patients with indication to the treadmill exercise test. There is an excellent relationship between costs and benefits associated to high sensitivities and specificities in the diagnosis of ischemia. This can lead to the preferential use of this technique, in the opinion of the authors, when it is indicated and in all patients that can do exercise.
