Performance, Interpretation, and Application of Stress Echocardiography in Ischemic Heart Disease

For treadmill exercise protocols, images obtained at rest and immediately after exercise should be compared side-by-side using quad-screen format.
For pharmacologic stress echocardiography, images from peak stress stages should be compared to rest, low dose, and prepeak or early recovery stages using quad-screen format.
Obtaining data from multiple cardiac cycles at peak stress enhances the accuracy of test interpretation. For continuous recording of rest and stress images, the use of digital recording software is preferable to recording on videotape.
