What is a Dobutamine Stress Echocardiogram
Dobutamine affects the heart in a similar manner to exercise. It increases the heart rate and blood pressure and makes the heart beat stronger. The rise in heart rate increases the oxygen demand of the heart and helps to determine if the heart muscle is getting enough blood and oxygen.
What preparation is needed?
How is it done?
An intravenous line (small needle) will be placed in your hand so that the Dobutamine can be administered. Uncommonly, other medications may be required in order to increase or decrease the heart rate.
The dose of Dobutamine starts very low and will gradually be increased until your heart rate has reached a minimum of 85% of its maximal level, or sooner if the test is positive.
During the test you will be lying on your left side and images of your heart will be taken before, during and after the Dobutamine infusion.
How long will it take?
