Background: This investigation was designed to determine whether transient wall motion abnormalities due to myocardial ischemia induced by walking could be detected by ambulatory echocardiography.

Methods: Two groups were studied. Group 1 consisted of 10 males (mean age 34 years) who had no symptoms of angina.
