Dobutamine Stress Test
This closely-monitored test helps to determine how well a patient's heart is pumping. It also can detect the presence, and/or establish the significance, of blocked arteries.

The Electrocardiogram (ECG) Technician places small disks (electrodes) on the patient's chest which are attached to wires (or leads) that connect to an electrocardiogram (ECG) machine. The ECG technician then uses sound waves through a transducer (a wand-like device) to look at moving images of the heart at rest.
During this test, the patient is given a medication called dobutamine through an intravenous (IV) line. This will cause the heart to work as though the patient is exercising. Ultrasound images of the heart are recorded both before and while the patient is receiving dobutamine. There is a recovery period of approximately 1 hour after the test.

The Dobutamine Stress Test takes approximately 90 minutes to complete.
