An echocardiogram is a test that is used to evaluate the heart's capacity and structures. A stress echocardiogram is a test done to survey how well the heart functions under pressure. The "stress" can be activated by either exercising on a treadmill or a medication called dobutamine.

A dobutamine stress echocardiogram might be utilized if you can't exercise. Dobutamine is placed in a vein and makes the heart beat quicker. It impersonates the impacts of activity on the heart.

During the echocardiogram, a transducer conveys ultrasonic sound waves at a frequency that is too high to be heard. When the transducer is set on the chest at specific areas, the ultrasonic sound waves travel through the skin and other body tissues to the heart tissues, where the waves bob or "resound" off of the heart structures. The transducer gets the reflected waves and sends them to a computer. The monitor shows the echoes as pictures of the heart spaces and valves.

Why is dobutamine stress echocardiogram required?

Reasons behind getting a dobutamine stress echocardiogram (DSE) may include:

  • To evaluate the heart's capacity and structures
  • To additionally evaluate the level of known heart valve disease
  • To know the limits of safe exercise before you begin cardio rehab or are recovering from a heart problem, for example, a heart attack or heart surgery
  • To assess the cardiovascular status before a heart surgery

There may be different reasons behind a DSE.

Which doctor to consult?

You will lie on your left side on a table or bed, however you may be requested to change position during the test.

The dobutamine drip will start at a rate that is determined by your weight. The rate will be maintained until the maximal dose is achieved.

When you have achieved your target heart rate or the maximum dose of the dobutamine, the drip will be stopped. Your heart rate, blood pressure, and ECG will be observed for 10 to 15 minutes until they have come back to the normal state. Last echocardiogram pictures will be taken.
