Non Invasive Cardiology

Dobutamine stress echocardiography (Dobutamine Stress ECHO) is an alternative to treadmill stress testing for patients who are unable to exercise. In this test, a medication called dobutamine is administered intravenously to increase the heart rate and simulate the effects of exercise. Echocardiographic images are taken to assess heart muscle response under stress. It helps detect coronary artery disease and assess heart muscle viability.

Why Is Dobutamine Stress ECHO Done?

• Patient unable to exercise

• Suspected coronary artery disease

• Evaluation after heart attack

• Assessment before major surgery

• Reduced heart pumping function

Procedure

The test starts with a resting echocardiogram. Dobutamine is then administered slowly through an IV line to raise heart rate. Heart images and vital signs are continuously monitored. The test lasts about 30–45 minutes and is stopped once the target heart rate is achieved or symptoms appear.
