Your doctor has asked that you have a dobutamine echocardiogram (dobutamine echo) to measure your heart’s tolerance to work and the heart wall movement when it is working very hard. This test is a stress test of the heart using the medicine dobutamine to make it beat faster and harder. An echocardiogram is performed during the test. During the test, your heart rate is measured by an electrocardiogram (ECG), and your blood pressure is taken while you are being given the medicine. The test, which usually takes one and a half hours, is performed in our office.
