A dobutamine stress echocardiogram is a two-dimensional ultrasound performed before and after injecting the medicine dobutamine to induce a physiological stress response.
Dobutamine will be used in place of exercise if there is a reason that an exercise stress test is not possible.
Through a hand-held transducer and gel applied directly on your skin, ultrasound uses non-radiation sound wave technology to create an echo image of the organs and vessels in your body.
The purpose of a stress echocardiogram is to measure electrical activity of your heart and how it responds to different levels of stress.
