Stress Echo (Dobutamine)
A Dobutamine Stress Echocardiogram (sometimes called a stress echo with medication) is a heart test used when you are unable to walk on a treadmill to the required level. Instead of exercise, a medication called Dobutamine is given to make your heart beat faster and harder, similar to how it reacts during physical activity. This helps doctors see how your heart works under stress and check for heart disease.
What happens during a Dobutamine Stress Echocardiogram?
- Medication infusion: Dobutamine, a short‑acting medicine similar to adrenaline, is given through a small needle (cannula) in your hand or arm.
- Heart monitoring: Your ECG (electrical activity of the heart) and blood pressure are checked throughout the test.
- Ultrasound images: Pictures of your heart are taken before, during, and after the medication to see how your heart responds.
- Time required: The test takes about 60 minutes.
- Side effects: Side effects are rare and usually mild, and resolve within 30-60 minutes post test completion.
