In recent years, stress echocardiography has gained broad acceptance as a non-invasive method for the diagnosis of coronary artery disease. Facing different protocols, dosages and instrumentation, official guidelines for the performance, standardization and quality control of stress echocardiograms are needed; however, so far they are not available. This paper recommends the type of personnel and technical equipment needed for stress echocardiography laboratories, based on experience gained during more than 2000 stress echocardiographic procedures.

To perform stress echocardiography, a cardiologist and a technical assistant — both well trained over a large number of tests — should be involved. The laboratory must have basic equipment such as a 12-lead ECG, blood pressur monitoring capacity, a treadmill or bicycle for ergometry, a precision intravenous delivery system for pharmacological stress testing as well as an adequate echo table; additionally, emergency equipment is mandatory.

The ultrasound machine should contain transducers with high 2-D resolution; most important is a digital image acquisition system which facilitates performance and interpretation through side-by-side display of synchronized rest and stress images. Finally, there is a need for proper patient preparation and the obtaining of informed consent.

Key Words: Stress echocardiography • technical equipment • digital imaging • exercise testing laboratory
