Exercise echocardiography: detection of wall motion abnormalities during ischemia.

13 patients with angiographically documented coronary artery disease and 11 age- and heart rate-matched normal volunteers (total n=24).

Echocardiography during supine bicycle exercise at increasing work loads until angina or ischemic electrocardiographic changes appeared.

Echocardiography at rest, and comparison with normal volunteers.

Echocardiographic indices of regional left ventricular function (systolic septal thickening, systolic posterior left ventricular wall thickening, maximal velocity of diastolic wall thinning, percent systolic change in left ventricular internal diameter).surrogate
